What a dickhead. 

Surveillance footage caught a teen tossing a lit mortar into Press Start, a gaming arcade and bar in South Dakota over the weekend. According to Reddit user murderedbyaname, one of the security guards allegedly sustained burns to her arm as a result of the mortar. 

Rapid City police in South Dakota have yet to make a statement on the incident, though many people on Reddit claimed an act such as this could be investigated by the ATF as federal agents don't play when it comes to "destructive devices" and that if the teen could face "domestic terrorism" charged.

What is mostly likely not a case of domestic terrorism, but instead some jack-off kid getting a bit too lit with his pre-July 4th preparations, the point still stands, kids are dicks. 

An image of the ceiling of Press Start shows the extent of the damage and makes me think two things: First, great fire proofing from whoever contracted the building, and second, this kid is lucky it didn't burn down, or will when he's caught.  

Don't be an idiot this Fourth of July. And don't be a dick either.
