So in other words most CCW holders are incompetent and dangerous?
It looks like it's even dangerous to go to an indoor range.
And that's without factoring in the possible mental immaturity or instability. Now arguing over a parking space makes you draw your weapon.
It's not real dangerous at all. You don't get many accidents at ranges when you consider how many go. You get do get suicides occasionally,, and at rural public ranges you get the occasional murder because criminals know they're good robbery spots if they find someone alone.
What people do do at ranges is screw around a bit, because they're not messing up their own property. You get guys shooting their most powerful stuff that they've only shot one or two times before, or you get them practicing trick shots. The most common serious range injury is someone shooting themselves in the leg when drawing the pistol.
The ceiling shots are usually new shooters or non-shooters (some people go on shooting dates, etc....) that are holding the gun up getting ready to shoot, then get scared by someone shooting in the next booth.
Also I wouldn't consider police better shots either. You'd have to check for Sweden, but here in the States, many police only shoot once or twice a year to pass proficiency exams. Also since most personal shooting are up close (less than 35 feet) one could argue that it is nerves that keep people from being good shots at a certain point. Historically only 10-20% of people were willing to shoot at a human with any type of deadly intent.
