Dirty Tricks:

1) Why are you being difficult?
2) Are you ok or are you mentally ill? (gaslighting)
3) Don’t address issue (personally identify) but point to police car
4) Don’t have reasonable suspicion but make up far-fetched scenarios: don’t match the description but could have changed clothes
5) Always have to have the last word, in a disingenuous way
6) Attempt to physically intimidate
