The digital technology is now in the hands of police officers. Well, Beaumont Police Department is making use of the advanced digital technology by installing in-car digital video system that rolls back three minutes from the moment officers turn on their lights and sirens, grab a shotgun or turn on a wireless microphone. The whole of the data is downloaded in the station. Now, police officers have a way to defend themselves as they could prove actually, what happened in the meantime of an incident. The best part is that the laymen don’t need to worry about the physical harassment and the humiliation. Sadly, not many police departments are adopting the technology since the cost of implementing the digital video system in a single car costs between $4,000 and $7,000. That is really too expensive.
