arrest the killer

The problem is that our "justice" system will only arrest the specific killer, one person. Other people could only be arrested if there's a direct link between them and the killer, and they're smart enough to not leave a trail.

All the people making doxxing target lists, still safe from prosecution. All the people saying "Charlie Kirk deserved to die!" are safe from prosecution. All the political leaders on the left directly or indirectly inciting violence are safe from prosecution.

If they can find 20 people willing to spend the rest of their life in prison for the cause, they can kill all the prominent leaders on the right. They don't even have to spend the rest of their life in prison, because some future Democrat President or governor can be counted on to pardon them.
