For my part, I have no problem with red flag laws in principal but this absolutely depends completely on exactly how this is implemented. It said in the article that it is adjudicated by a judge...Fed judge, local state judge (ah, I think red flag laws are at the state level, no?)? And, is there a process for appeal and exactly what evidence is required to deny someone their constitutional rights because they have been found mentally incompetent to own a firearm. Just your ex-wife saying you are crazy? Hmmm?
I cannot support anything like how NICS works...your right to purchase a firearm is totally determined by the FBI. Yeah, there is an appeal process....yeah...appeal to the FBI/NICS' "appeal team"...yeah, the very same FBI/NICS who denied you in the first place. No provisions for any actions outside of the FBI...like for example, a court of law.
Then there is the situation of endless "Delay" status....for which you have zero recourse. You can't appeal a Delay and your FFL is has absolutely zero obligation to release your item after the 3 day period. You are just fucked and will spend a lot of money on a lawyer....which may or may not help.
And then there is the domestic abuse and restraining order crap where your pissed off GF can utterly fuck you just with a statement of abuse or getting a restraining order on you.
So, any red flag law application needs to be applied by a court of law, with evidentiary criteria well defined, with an appeal process also, for me to support this.
