I'm not familiar with "the kids who filmed the black guy drowning."  You're saying some kids let a guy drown for political reasons?

But anyway, I'm sure we could name right-wing and left-wing killers all day.  We'd probably end up fairly even.  

But, the left really seems to shine when it comes to rioting and destroying property.  They far exceed any damage by the right.  And once again, this story is about vandalism and destruction, not murder.
