These two mutants targeted the victims because they were WHITE. They also spouted racial hatred while commiting their vile deeds. This makes it a hate crime.
Their behavior makes it a hate crime.
Some 10 - 15 years ago several white teenagers (both male and female) hopped a freight train to Chicago. Unfortunately for them, they naively got off in South Chicago (a Black area) - they were immediately set upon by a pack of hyenas. The similar behavior from the Chicago variety of hyenas. Rape, racial slures and taunts, then murder. One or two of the teens survived to tell the horrible details of that nightmare.
Guess what? Again media silence and no charges of "hate crime" were lodged against these animals.
Of course it's a hate crime for the victims and their families to harbor any negative images of the Blacks.
