Being an LEO has no bearing on whether you enjoy guns on the side or can shoot well. I would wager that the same percentage of non LEOs that like guns and can shoot well applies to LEOs as well. If 2% of America were gun enthusiasts and shot regularly, I would bet it would be no more than 5% within the LEO community as well.
LEO's have lots of tools and skills that they have to be proficient with, but not an expert at, to do their job. Fierams are one of those things. For example:
1. I am proficient with a handgun, but I know that people,( including other LEOs), who are really into target shooting are going to be better shots than me.
2. I am proficient at hand to hand combat, but I know that people who are really into martial arts or other organized fighting, are going to be be better fighters than me.
3. I am proficient at interviewing and interrogations, but there are going to be people who are really into interviewing and interrogations, who constantly seek additional training, and who do it more, who are going to be better than me.
4. I am proficient at wiretapping, using cell phones to track people, and GPS tracking, and night vision gear, but I know that tech agents, and electronics buffs are going to know more about it than me.
5 I am proficient at surveillance, but I know that people who have been on dedicated surveillance teams for years, whether LEO's or private detectives, are going to be better at it than me.
6. I am proficient at breaching doors, and conducting high risk entries and warrant services, but I know that people who are on dedicated SWAT teams, or who have been doing it in Iraq several times a day for the last year, are going to be better at it than me.
7. I am proficient at high speed driving and emergency vehicle maneuvers and operations, but I know a stunt driver, or professional race car driver, is going to be a lot better at it than me.
8. I am proficient at the identification of different drugs, but any laboratory chemist is going to be better at it than me.
9. I am proficient at crime scene investigation, but any person whose only job is crime scene processing and forensic examinations, is going to be better at it than me.
10. I have received training in traumatic first aid, and am proficient in it, but any EMT is going to have more knowledge than I do.
11. I am familiar with helicopter operations, and know the range and capabilities of several different helicopters, MH-60, SH-50, Longrangers, A-Stars, etc., but any helicopter pilot is going to know a whole lot more than me.
And, on and on. To people who like shooting guns, their image of an LEO's job is focused on his gun. The reality is that it is one tool in a very large toolbox, and that while individual officers or agents are often expert in the use of one or two of those tools, no one is an expert in the use of them all.
