Are cops ever scared...?

I don't know about courage and all that malarchy... I guess it is a spur of the moment situation, and knowing if you are in the right, or if you should have your shit kicked...
I have witnessed alot of chicken shit acts in my life. When I was a bouncer, I once handled a guy that knocked out a girl in a mosh pit. But, once in high school I chickened out when I witnessed a friend snatch his girlfriend up by her hair in between classes (my saving grace is that they were surrounded by a million on lookers in the hallway). I regret not reacting to this day.
The saying amongst incarcerated people, is that law enforcement is full of people who need a badge to regulate, but without it, they would run scared. I'm not sure that is entirely true, but I have seen some people just like that often enough to make my blog.
I had a guy, cop, that was my friend. Supposedly. Then on a drunken night of retardation, he made the mistake of trying to move on my wife. I, being drunk on tequila as well, contemplated my different weapons of choice. One, was the obvious, but knowing he had one racked and ready to roll, I decided against it (smart). Two, was strangulating him. I have a fairly good idea that I would be successfull, but I didn't feel that I should go to jail for his stupidity. The third option was my choice.
I walked into the room, and surprised everyone present. Douche bag thought I had gone to bed, and when I asked him "WTF?", he scrambled. I told him to get out ASAP, and he tried. If I wasn't so pissed, I would have laughed. It was like watching a mentally impaired (oh that's right, he was) running into the same wall repeatedly, and not being able to get through.
Douche bag finally was able to locate his shoes, and his keys, and stumbled into the night. Now, he had been apologetic, and even had the "deer in the headlights" look in his eyes, but as he stepped out into the dark night, he left me a "fuck you". As the door shut, I lost my composure.
I opened the door, and found him stumbling to his car. He was fully dressed, and in a fight, would have been better suited to grapple without being injured. Douche bag was also, however, more drunk, because I had slept a little off, and he had continued. I on the other hand, was wearing nothing more than my tattoo's and my gym shorts. I was so heated up, I didn't care.
He saw me coming, got into his car, and started running his shitter.
I thought twice, and told him to "get the fuck out of (there)". I now knew he had his gun, and he started to open his car door, while talking shit. I closed the door on him twice, and told him two more times to bail. Finally I told him I was going to call the local PD and report a drunk driving cop in a cop car.
This sobered Douche bag up enough, and he left.
Am I a dick? I am when I'm around a pussy. Without a gun, he had fear in his heart. With his gun, and in his department ride, he felt like King Shit. I'm gratefull that I was sober enough to think of the consequences to the possibilities. Douche bag was not worth losing my career, my family, or my life. Although many friends think that it knocked my "manhood" down a level for not fucking him up, I'm trying to realize that I made the correct choice.
I saw a scared cop, and I was satisfied. He and I know the truth of what could have happened.
Are there cops with tin badges? Absolutely, those are the scared cops... Then you have those of us who live life with nothing to prove, and know it.
