No idea but this is my entire problem with the people who on the one hand don't want law enforcement to ever come near them and at the same time want law enforcement to have perfect anticipation of who will be a threat and be all up in THEIR business.
What you're learning, Kyle, is that what justifies police scrutiny is not as cut and dry as we all would like. You can't say cops should never scrutinize you and at the same time demand they be perfect in determining who they can lawfully scrutinize & that is an actual threat.
Since when does the police investigate someone for going to the gun range? He did not threaten a sole and he gets a visit but the shooter threatens to kill people on video and they just ignore him.
They did a great job investigating the Parkland Shooter, the Pulse Night Club Shooter, and this last Waffle House Shooter! All were known to be a HUGE RISK. All continued to have access to weapons. #SAD
