I doubt very much that there were outstanding arrest warrants on him. An arrest warrant is for criminal offenses, and a city fine for weeds and unpaid property taxes is not exactly a criminal matter. I may be wrong on that. What I don't understand is how his security company employer found out about his unpaid fines. It may be that the city's computer records showed his private police commission and his employer data.
We had one last week here in Sacramento that saw three people B&E a car. He called his supervisor and they went toward the car. The rats entered the car and attempted to run him down. One shot to the upper chest killed the driver. All the Apt residents were very happy. The talking head asked the apt manager about the legal shooting. He said he didn’t know he had an armed guard. Poor fellow, pull a trigger and fire yourself.
