The extent to my knowledge is limited within forensics though. I took a class in college. Interesting field though.
And what if the person has a replaceable barrel? If I planned on shooting someone, I would absolutely use a replaced barrel to do so. Flocks are easy to replace, available on eBay, and can be fitted in seconds.

My point again is, not everyone is stupid, and will find ways around the limited power the ATF has now.
