On a related note, why must every single police officer be armed? At the very least, why does every officer need to carry it at all times? I can see 1-2 on a shift carrying for urgent situations but arming everyone invites them to pull guns on people.
I can't imagine you put my thought into this statement or, at a minimum, have no one close to you who is or was with the police. I have several close friends who are with various "local" departments (Calvert, Charles, MD State, District of Columbia). Some of these jurisdictions not only have you armed while on duty, some want you armed while off. Some of these cops (DC in particular) are targets to the extent that they are not allowed to be in uniform while off-duty .......... while driving to / from work. They are targets.
More so, they are trained and relied upon to protect the community - whether working or not. It would be asinine to think they were unable to stop a situation because they had to leave their gun in a lock box at work at the end of the day. Most consider themselves "on-duty" 24-hours a day though only being paid for 8.
I'm also curious how a routine traffic stop would work. Would each officer need to call in for their armed supervisor before approaching the car he pulled over for the missing taillight? Come on now.
