Hypocrite

Sanctimonious person: Someone, that despite others tragedies, does nothing, takes no action nor speaks out or says a word at all, until something (the same exact misfortune i.e. tragic mass shooting) happens to them!

The people, blaming & wanting to outlet guns that have been in production since 1959, that are marching on Washington are nothing more than self righteous hypocrites that only decided to take action when hardship befell them!
