Non-threat criminals should not be attacked unless it's a situation exempted by cop rules such as the non-threat criminal is swimming, flying an aircraft, etc. Given that you've been already PSOed for attacking non-thread criminals in the past, the PSO won't be removed. I suggest you read /crules to avoid being punished again because the next PSO most likely will result in a public service (cop/firefighter/medic) job ban.
