Good job!!

We're at a convention in Kearney, Nebraska.

On Friday evening after dark, the son-in-law of some of our friends was unloading some convention stuff from a trailer in a dimly lighted area behind the convention hall. One of the local "ne-er do wells" accosted him with the intentions of mugging him for what he could get. He picked on the wrong guy.

Our friend's SIL simply decked the guy, then sat on him to hold him down while he called the police on his cell phone.

The police showed up, commented, "Oh, him again", and hauled the guy off.

Sounds like that guy needs to find a new line of work.

"Oh, him again"
Right there is the irony of your whole post. He'll post bail, plea bargain down, and be out on the street....again.
I had some items stolen from me about 2 1/2 years ago. By sheer luck of the law enforcement and some downright stupidity of the crook, he was caught.
My items that were recovered (actually two vehicles) sat in an impound yard for several months. I was repeatedly told that I could not have them back until the chief of police, the lawyers and the judge signed off on the items. So after several months, I get a phone call on a Tuesday and was told that my items had to be out of the impound yard by Thursday....or else they would go to public auction. Impound yard was over an hour away. So I took off a day of work, had to pay the impound yard $150 (out of my own pocket) to get my vehicles out and put about 300 miles of wear and tear on my truck and trailer to bring them home. The cops told me that I was lucky because they waived the towing fee.
On the victim compensation form that I filled out, I clearly stated that I put priority on the guy serving time verses getting compensated. (This guy had stolen $100K of items that he had stockpiled when he was caught) I also found out (through other sources) that this guy was a repeat offender, but when I told that to the prosecuting attorney, they acted surprised.
The DA kept me in the dark about most of the trials, which occurred in two separate counties, although I got a letter saying that I could voice my opinion to the judge before sentencing.
The sentence given to this guy? Time served, which, thanks to getting bailed out, was less than a day and restitution for the victims. The DA told me that they pushed for restitution instead of time because this guy had a really high paying job and if he served any time he couldn't make restitution.
How much restitution have I received? Not a single penny.

Often when someone gets off like this they are a police informant or a relative. Or a good customer for a drug dealing judge.

I was approached several times in the late 70's by a cousin, he wanted me to "invest" in a drug deal. I always refused, I knew he was a user, and figured that he simply would take off with money. Not to mention that I wasn't going to be a drug dealer...

I found out several years later that he had been a paid snitch for years, working for the cops. He had put a lot of folks in jail, mostly folks who never had problems before. He ended up in prison, and almost got killed. They moved him from Michigan to Arizona to protect him. He did 4 years in a federal pen, but he can't come back to Michigan, I guess ever!

a typical experience. Went thru same thing, impound charges $25/day per item. $300 in charges before I even found out they had it. Thief was arrested but charges dropped after few months. It was mine, he stole it. They seized it in his yard, he confessed. Dropped because not enough evidence! What a system.
