The best way to find out is to ask. You can find yourself in a lot of interesting conversations that way, if you go about asking properly. I asked once and found out that my local Sheriff's Department requires that each Deputy supply their own firearms. The one I learned this from was carrying a 9mm Baby Eagle, which is what prompted me to ask about it.
As far as LEO viewing firearms as making their jobs more dangerous, I recently had an LEO encounter on my grandmother's farm. She told a buddy of mine that we could go out and shoot in her field, so we did. After a while a Sheriff's Department cruiser pulled in and asked us if we had permission to there, etc. It turns out that a neighbor had gotten concerned about the gunfire (since my grandmother is about 70) and caled the cops to make sure nothing was up. They ran our licenses just in case, and while they were waiting for that to come back, one of them asked if we minded if they handled my buddy's WASR-10 and my Marlin 1895. Everything came back clean, they told the dispatcher that we had plenty of backstop, not shooting onto anyone else's property, etc and told us to carry on as they pulled out. Not exactly sounding like an anti response to me.
