In Chicago any officer who fires his/her weapon on or off duty will have to submit to random alcohol tests. They also are making it where they cannot drink alcohol 4 hours before their work shift. I don't know if I agree with the first part. The union is the one asking for the test I guess to protect them, but I know where I live there have been a lot of police shootings and people get so mad and want to know why they couldnt have used another method, but I always think what would I do if I was in that situation. They need to protect their lives.

That's really true.  It's not putting very much faith in our officers if they are assuming that alcohol is always going to be a factor.  There are some really crazy people out there, and if police are given guns, then they shouldn't feel reluctant to use them. 

NY does the same test after a shooting is involved and either this week or last week an officer tested positive after he shot at someone off duty. His department is sticking with him though saying he did the right thing and took action when it was needed. He is back at work carrying his badge and gun. At least his police commissioner is standing by his side, maybe officers will be more careful when they are out, but again he wasn't on duty drinking so he just happened to be at the right place at the right time and he did what he thought he needed to.
