Never use gun mods for self defense/duty....they will be used against you in court!

via The Truth About Guns...

Attorneys for the victim, Daniel Shaver, argued Brailsford was malicious during the shooting and raised questions about the gun used.
The Maricopa County Attorney’s Office said Shaver was on his hands and knees when Brailsford shot him five times inside a Mesa hotel. The gun used was a personal AR-15 assault weapon that had been approved for service use by the Mesa Police Department. However, Mesa police noted that their investigation of the shooting turned up a vulgar inscription on the rifle that doesn’t meet department policy.
“Inscripted on the officer’s gun, and I hate to use profanity, but it said, “you’re f*****,”’ Laney Sweet, Daniel Shaver’s wife said.

If you use a weapon during the days of "rule of law" then they need to be as pristine as possible.  As you can see from the story at the link, even something so unimportant as inscriptions you put on your weapon will be used against you.  In this case to go to the state of mind of the LEO involved.

Don't get it twisted.  Protecting yourself comes first but adding certain "cool things" that don't increase accuracy and serve only as conversation pieces is just a bad idea.

Have a ball with things if widespread or even localized disorder results but be aware of the issues with courts, perception and bling you put on your
weapons.

As a side I'm wondering how extended capacity magazines are viewed (not normal, but truly extended)?  RMR sights too.  How far down the rabbit hole does this actually go?  One last thing.  I'm not defending the cop.  If the story is true then he executed a person in cold blood.  I am taking a good look at the tactics being used against him in court though.
