A glance... A headline and periodical. No real details.

Yup. Sometimes there is no choice like a medical emergency when you need to call an ambulance. Then the cops tag along to take advantage of the situation and start roughing people up / making up charges.

Statistics might be a good starting point but they are one dimensional (justifiable murder or not) and are bias (who determines that). There are circumstances where it's justified but it sure as shit isn't 99.9%. People's are upset because cops killed a kid during a situation which at a glance does not appear to be life or death.

Cops are human. They have bias, corrupted motives, adrenaline, fear, poor training, etc. No one wants to see someone in jail for an accident on the job. Mixed feeling on how it should be handled or prevented.

None the less someone's kid is dead.
To write is off as justified because it's a cop is bull shit.
