90% of law enforcement cant shoot worth a dam. Ive seen countless times cops at training classes that either couldn't hit there intended target or couldn't operate there weapon(s).
In a Magpul Dynamics Pistol class i took there where 5 cops. 3 out of the 5 where horrible shots and where there just because there department paid for them/made them go. One of the guys consistently had trouble with simple malfunction drills. The other 2 cops couldn't keep a group/consistently hit there target to save there lives. It was BAD!
At shooting ranges around here aswell I've had the privilege of seeing some god awful shooting from LEO.
I got pulled over by Redmond PD a few months back. The guy asked me if i had any guns and i told him yes sir as i handed him my DL and CCW.
The gun was in the center console and he went to the other side to take it out/disarm it. I told him that there wasn't a round chambered and he goes "Ok". Next thing i know as i am watching him clear it he proceeds to pull the slide back to check and chambers a freaking round. He forgot to drop the dam magazine. You could tell just by his demeanor that he was nervous the whole time while handling the gun. He acted like it was some foreign object he's never seen before. I was in amazement. A M&P Compact no less.

That car was riddled with bullet holes. Theres rounds down near the license plate. They riddled other cars down the street and hit the garage. Holy chit, they need more quals/training.
On the other hand I've seen some truly remarkable shooters and fellow friends that are LEO who could take out a fly at 20 yards. They take there training seriously and are constantly taking classes/shooting on there own dime to keep proficient. In this time of budget cuts/ammo shortages cops are going to have to train on there own dime. Its only going to get worse as Departments across the country are suffering from severe ammo shortages where they don't have enough for practice/quals. They need to ask DHS for some of there 4.5 billion Hollow Points that they bought...
