The REAL ISSUE with the NYPD is their lack of training! Not only do they get a rush through course on shooting and firearms (IMHO) but the average Officer there does not discipline themselves to practice enough. It's not just my opinion, it's fairly obvious if you look at the shooting history they have had over 30 years. Pathetic!
Training & constant practice is the key to preventing accidents - not making trigger pull weights ridiculously heavy. Kind of like making an accelerator pedal in a car very hard to push to reduce speeding.
There's the truth! It does take training and then practice to be proficient and safe with any firearm.
