    7/7/2015 · Security
    A report of shots fired at the Navy Yard in Washington, D. C. brought a huge response from law enforcement from all areas. The response was immediate and overwhelming. As it turns out, the report was false. The incident remains under investigation at the time of this writing.

    5/26/2015 · Security
    Coordinating security for corporate offices, hotels, apartments, convenience stores, and just about every other possible location can have its challenges. Coordinating security at major events, however, is especially challenging. This article will focus on some of the challenges I faced when coordinating security for several events and locations in Houston, Texas for Super Bowl XXXVI.

    Not long after I promoted to sergeant, I was training in a patrol division. I was riding with another sergeant when we received a call from two patrol officers. They were at an apartment complex and had chased a male into an apartment. They requested a supervisor go by with them. So, as part of my training, we went.

    I have read a number of books, studies, and court cases in my career to support the fact that eyewitness identification, by itself, is never sufficient enough to send a person to prison. This is not news. Over the past 20 years, more and more people are being exonerated for violent crimes due to DNA . This article is not to rehash old arguments. Instead, it is more of a reminder to investigators everywhere to not finalize a case, charge a person, and send them to prison based solely on an eyewitness' identification.

    3/26/2015 · Law Enforcement
    During my 22-year law enforcement career, I became involved in countless situations in which I personally dealt with people in mental health crisis. My first incident involved a Hispanic male armed with a pistol. I learned a significant amount from that single incident: so much, in fact, that I made the decision to join the Houston Police Department's Hostage Negotiation Team. The techniques I have learned over the years can be applicable to almost anyone, at any time, in just about any situation. In the following paragraphs, I will recount a few incidents in which I was involved and discuss the techniques used to end each the situation safely. Understand that this is not a specific "how-to guide" that may be applied to every situation. Instead, the use of these techniques will simply allow a person that becomes aware of a certain situation - to be able to attempt to stabilize the incident prior to first responders' arrival.

    In 1982, a foreign diplomat was assassinated a few blocks from a Federal law enforcement agency office. There were no computers, cell phones, or pagers. Within 18 months, investigators made 18 arrests and put two major terrorist organizations out of business. This article will explain how this was accomplished with no digital technology.

    This article will discuss the attempted management of a convicted cooperating witness who continued his cons while working with the government. He was a constant challenge with many interesting events. These types of people do not change their personalities just because they are "cooperating". The first time I met him he said, "You'll like me in 15 minutes". He was right.

    Homicide cases in which the victim cannot be identified are difficult to solve and profile. This article will discuss the importance of victimology in a homicide investigation.

    Violent Crime has increased dramatically in the United States in the past 50 years. Many of these crimes involve serial homicide and rape which are especially challenging for investigators and experts since the perpetrators are usually experienced at what they do and don't leave many clues at the crime scene (if it can even be found). Plus, these crimes have a tendency to gain a lot of notoriety from the news media and public which results in intense pressure on the police department or investigating agency to solve these crimes quickly.

    6/5/2014 · Psychology
    Many times investigators and experts are confronted with cases which are equivocal: uncertain or questionable. For example, a death appears to be suicide but may actually be murder staged to appear to be a suicide. There are also cases which appear to be suicide but are actually accidental deaths. This article will provide a questionnaire for investigators and experts when confronted with these types of cases. The questionnaire is provided to attempt to determine the mental state of the victim just prior to his or her death and whether or not the victim was suicidal.

    John Delorean was a very successful executive at General Motors and was known for developing the Pontiac GTO, the Pontiac Firebird, Pontiac Grand Prix, Chevrolet Vega, and the DeLorean DMC-12 sports car, which was later featured in the 1985 film Back to the Future. In 1982 Delorean was arrested by the FBI for drug trafficking. "The alleged drug trafficking was supposedly an attempt to raise funds for his struggling company, which declared bankruptcy that same year. He successfully defended himself against the drug trafficking charges, showing that his alleged involvement was a result of entrapment by federal agents". Delorean was found not guilty on August 16, 1984.

    This article will focus on how to research FBI policies and procedures for the operation of informants. These documents are available to the public through the Freedom of Information Act (FOIPA). Researching FBI records can be very difficult and frustrating since many of the records are not searchable once you find the record you desire. Lawyers who need help researching these records may find that it is more cost effective to hire an expert to find the information they need.

    Many young people make bad decisions which may follow them the rest of their lives and close doors to great opportunities as they progress through the work force. The bad decisions which seem like a "fling" at the time now have disastrous consequences when the young person has an interest in a job that requires a security clearance with a background investigation and polygraph.

    Violent Crime has increased dramatically in the United States in the past 50 years. Many premises liability cases involve violent crimes that could have been prevented if the landowner had taken the appropriate precautions based on industry standards. Foreseeability is important in determining whether violent crime could have been predicted based on past violent events. This information is easily obtained due to advances in computer technology. The public can now access this information in most locations throughout the United States.

    False allegations are seen in several types of cases and are very problematic for police since extensive investigation must be conducted to corroborate the victim's allegations. A great deal of resources can be wasted in these investigations since the alleged crime never took place. One study indicated that false rape allegations constituted 41% of all forcible rape cases in one police department. There are indicators of false allegations that may help police and experts determine whether a crime took place.

    Your personal security is based on your life style, and personal decisions. The Risk Continuum will assist you in determining your risk for becoming the victim of a violent crime. Minor changes in your life style may have a major impact on whether or not you will become a violent crime victim. There are many risk factors that you should consider when trying to reduce your level of risk.

    Victimology is defined as an assessment of everything that can be known about the victim of a crime, and is a critical tool for the investigator and experts which can lead to the quick solution of a criminal case or the resolution of a premises liability matter involving a violent crime.

    9/5/2013 · Law Enforcement
    Offenders will sometimes stage a violent crime because they know that they need to re-direct the investigation. The problem for some of them is that they are unfamiliar with crime scene investigation procedures and may make themselves more obvious as a suspect.

    8/19/2013 · Law Enforcement
    Defendant was observed driving a vehicle with a cracked windshield and a broken driver's side rear tail lens. He was stopped by the police for equipment violations and was asked various questions which indicated that he might be transporting money from an illegal drug transaction. Police asked if they could search the car and the defendant refused.

    The assessment of victim risk by an expert witness in a premises liability case may become critical to the successful outcome of the case. This article provides a Daubert style methodology for determining whether the victim was at low, moderate, or high risk for a crime of violence.

    As is probably true for many of us in the workplace, my career has not turned out quite as I envisioned it would some 40 years ago. More specifically, as a beginning graduate student in sociology, I had no idea I would eventually practice forensic criminology or be in a position to write about what follows. In fact, I had never heard of forensic criminology (FC) until years later and, I believe, neither had my academic colleagues. It was only after I began to practice as a forensic criminologist and to identify myself as one that the parameters of this fascinating area of expertise began to reveal themselves more fully to me.

    Social scientists play an increasingly important role in the prosecution and defense of both criminal and civil matters before the courts. An expanding area of forensic sociology and criminology involves the analysis of crime foreseeability and security standards of care as they relate to the question of liability for negligent security. Criminologists analyze prior crimes at a location and consider the totality of circumstances in order to determine foreseeability.

    Criminal or offender profiling in one form or another has existed for many centuries.
