So, given the number of "hate crime" accusations shown to be false, is it sound journalism to continue to use the phrase "all too common" in reference to mere -claims- of "hate" attacks, absent documentation of their actual occurrence?

Prosecution of false reports to police, instead of hand-waving and deflection, would grant those actually attacked more credibility. The bad apples (far more than one) are spoiling the innocent bunch deserving justice.
