How about: never attempt to take anyone high on fentanyl into custody. It is not worth the risk.
Suspects who resist arrest are usually under the influence of something. Fentanyl, bath salts, alcohol, etc.
Rodney King (1991) was arrested for drunk driving and tried to evade arrest. One of the officers thought he was lunging at him.
But how would cops know the erratic driver was on fentanyl or just drunk without pulling him over?
We just had a big wreck in Oklahoma when two meth heads ran their car up a steel electric pole. It hit the pole so hard the car did a double back flip back onto the highway. The pole did not survive.
Rodney King was believed to be on “Angel Dust”. Dusted, the cops called it, since tasers had no effect on him.
