C’mon, Hightower and Hooks were easily the most soft spoken of all the characters from the Police Academy franchise. Even Jones, though he could get loud with his signature sound effects, was quite soft spoken in regular speech.
Compare to Lt. Harris? Sgt. Callahan? Tackleberry!?!?!?!?
Sheesh! Why do I even have to spell this out?
I’ve got it! The OP thinks all Blacks are loud because every time a Black person has attempted to communicate with the OP in person, said Black person has had to result to the time-honored method of increasing one’s volume when speaking with the stupid.
