Listen. I’m going to explain it to you like you are five.
“This is America” is a phrase often used to lament police misconduct in the US. By adapting it I explicitly referenced US police misconduct, thereby saying “we have this problem too”. Only if you are ignorant or in bad faith could you interpret this explicit reference to the African American struggle against police violence as “this happens only in Europe”.
If there are mistaken assumptions they are yours and yours alone.
