I agree that LEO should be able to get what they need to get the job done depending on their environment; i.e. Lever gun, Semi-auto or whatever.
I will say that training is probably the most over looked aspect of it all. I used to work as a Nuclear Security Officer at the local Nuke Power plant, we were required by our head of security to qualify with 4 weapons each year. The M1-A, AR-15, Rem 11-87, and 9mm handgun. The NRC (Nuclear Regulatory Commission) only required us to qual with the handgun. We had to have 80% minimum for the handgun and rifles and only 50% on the shotgun. Plus we went to the range every 3 months for weapons training, or if you were on the Tactical Response Team (proud to say I was one

) you went every 45 days.
One of the local PD's also used the range and we found out that they only have to hit 70% minimum to pass their qualifications. Now as a citizen, I would like my PD to be able to hit 90%, but that is my .02 worth.
