They didn't toss anyone out after the what was it Beau vs Janelle shoving match that probably wasn't enough to get an assault charge filed, but came pretty close.I doubt any jurisdiction in the US would file assault charges over a drink tossed at anyone.
Is it nice? No.
Is it worth a couple of monthes in jail with fines and community service? No.
Threatening someone with a knife or tossing furniture, could be something the courts would take seriously enough to not laugh the prosecuter out of the court room.
I know I'd have a hard time voting back into office any DA or judge who went after a tossed drink thrower in court. Waste.Of.My.Taxes.
It ain't nice to do to others, but calling it assault?
