when you see someone with a firearm, what do you think? when i see an armed officer, i notice the gun. half funny story a friend of mine (who unlike me, owns and practices with firearms) about the first time he visited an indoor range. he asked the rangemaster “what’s with all the holes in the ceiling?” there were holes in the ceiling just ahead of the line you stood behind to fire downrange from. the rangemaster replied something about police coming in to practice for qualifying with safety holsters. overcompensate and i guess rounds go in the roof, but that type of holster does keep the weapon secure.
you seem to have no understanding about either firearms or the law. you don’t really have to learn. police do. in addition to that, police help people. it is their job. when they are incapable of doing their job or worse yet, obeying the law then it is the responsibility of our legal society to prosecute them for their negligence or misdeeds. note: just because a police car drives past you while changing a tire doesn’t mean they are not doing their job. it can be funny to have that happen. it can also end poorly when they can’t stop because their attention is already required elsewhere.
opening fire into a crowd is not their job. on that we agree. as far as what you wrote… it sounded like you want to live in a world without police. i might still be around. that bother you?
