I'm married to a retired Houston police officer - retired due to Crohn's disease, not age and my father is a Sgt with the constables here.
A couple of things - you never aim to shoot someone in the leg, hand, shoot the knife out of their hand, etc. If you miss (and think about how small a hand is), you or someone else might die. If I can get within 21 yards of you, you can not get your gun out of your holster and shoot me before I can slash you.
The traffic code in Texas regarding emergency vehicles is
here if anyone wants to read it. Basically, a peace officer on patrol is exempt from Texas traffic law even if that is not the 'letter' of the law. An officer on patrol is always "pursuing an actual or suspected violator of the law" by the nature of his job. They are looking for the bad guys, really. I swear.
My husband didn't work traffic and maybe wrote one speeding ticket in 10 years. You'd write one too, if someone was dumb enough to pass you on the freeway at a high rate of speed. It's not like you can't see the police car, right?
So anyway, if anyone has any questions about the police, I'll answer them as honestly and fully as I can. I readily admit that there are a number of people who should not ever be handed a badge and gun, but my theories on how to weed them out are apparently not popular (more pay, higher requirements).
