I mean if someone makes death threats to someone else they should absolutely have their guns taken away.

The thing is, this isn’t shown in the original post. Also, making death threats on its own is illegal, red flag laws aren’t required if the person making the report has proof.

Said victim could even get a restraining order if they were worried about violence, which won’t completely assure safety but will go down a process that actually uses due process and doesn’t violate anyone’s rights.
