Crystal Webb cringes whenever a patrol car appears in her rearview mirror. She also never wants to see the inside of a police station again.

Her personal experience with police, plus recent fatal shootings of unarmed black men by white officers, has led the Apple Valley, California, mother of two to ask: Who are the good guys and who are bad?

"You are the people I'm supposed to go to when I'm in trouble," Webb says of police.
