Criminal charges still possible:
The prosecution can appeal (and is) the judge's decision to throw out the weapons charge.

Civil case:
The victim and families can sue, but K. Rittenhouse is having money THROWN at him from crazy gun nuts and right wing MAGAs ,so it'll not actually punish him in any way.

Now, his friend who purchased the gun for him is DEFINTELY going to face charges - that case was on hold.

Don't be surprised if the GUN FUCKING NIT USA will let him off too.

Also:Look for dozens of copycat incidents in the coming years.
