If you sentence someone to jail time for twerking in front of or around memorials, you might be a douchebaggy backwards country. There's being sad and offended because someone did something in front of physical shit that houses memory for some, then there's arresting people for that act.
Doesn't matter if there is any emotional justification, arresting people over dancing is fucking dumb. Funny if you think about it, the powers that be for Russia during WW2 were fucking terrible and abysmal, then later on the Russian government punishes people for dancing in front of WW2 memorials.
