The cops in the town where I grew up were anything but brave.
That may or may not be. But you making sweeping generalizations of the entire law enforcement community is just silly. To put it lightly.
You making a judgement because of a snapshot you have of them, for their entire career is also silly. You said you had just one encounter talking to an Officer, and from this and observing however other many times, you made a judgement for that Officer, your town, and all Officers in the Country. Do you see how silly that is? Surely you've had a bad day, or moment and if all someone saw was that one snapshot of you, they would think you were like that all the time.
The fact is, Officers have bad days. They have personal problems, job problems, etc. That being said, it is not ok for them to bring that into work. However, it can be very hard not to at times. I'm sure everyone has snapped at someone, or done something they've regretted in the heat of the moment.
It is NOT ok for an Officer to break the law, bend the rules, etc just because they are "cops". But some do, that's a fact. There is a common saying, 10% of the people are 90% of the problem. Which is all too true. Most civilians do not interact with the Police at all, unless they are wronged. And it is the Officers job to conduct themselves in the highest regard at all times, leaving a good impression upon the community.
It can be very hard to do so at times, depending on where you work. I work on the "wrong side of the tracks", where there is a ton of gangs, drugs, prostitution, etc. You have to treat them differently that some upper class people, because they are street smart and can read you very well. They know the laws, they know what they can get away with, and they
try to push you to get you to do something wrong all the time. It's so annoying, but part of it.
I say all that to say this, yes some Officers are bad. Some give the rest a poor name. I can assure you that most are good, and do the right thing all the time. I know in my Dept that is the case, while not huge, has well over 400 Officers. Don't let the one bad instance you had with an Officer burn that bridge, and don't let that headline make you think we are all that way. As I said, priests, teachers, congressmen, etc have all been making headlines of doing the wrong thing. That doesn't mean that they all are. It's the same for Officers.
