The purpose of court security it to keep the public, the judge, and anyone entering the courtroom safe from any possible danger. Court security staff arrives approximately an hour before court convenes to conduct a search of the facility and to test certain devices. Their goal is to ensure safety by examining anything out of the ordinary that may pose a potential threat (i.e., hidden weapons, items or materials within the perimeter that may have suffered tampering, blocked emergency exits, etc.). Searching within the court room, around the building and in the court house parking areas is all part of the normal procedure exercised on a regular basis by the court security staff.
Contingency plans are in place to address security concerns for "high profile" trials. These trials would include cases that generate a significant increase in media attention, and those that carry a significant risk to either party regardless of the outcome of the case.
