So today (12/16/14), I was listening to School Safety Citywide 1 and I heard 5 10-13s/10-85s come over at different schools in different boroughs. Most of the 13s/85s were in regards to multiple 10-52s or 10-34s going on at that location. The worst one that I heard was at Leadership H.S. in Manhattan South confines of the 1st precinct. The agents were on the mikes trying to advise central of a student with a knife and other students involved in a dispute at that location. Simply put the agents were yelling for help and multiple SSD squads and bosses responded forthwith with 1st Precinct units. Nobody was collared and the perp with the knife went 10-90Z However I have some questions that maybe some could help answer: I heard multiple 13s/85s come over and only heard SSD squads respond but no UTF (Uniformed Task Force) squads respond or come over the radio, so I was wondering if UTF squads listen to SSD CW1 or if they or on the regular Citywide PD channels? Second, does anyone know the protocol for notifying patrol to respond to locations? Do regular P.D. unit have SSD CW1 in their radios? Third, How come School safety 13s/85s never come over S.O.D (ESU/AVIATION) frequency? Fourth, Who here thinks officers/agents calling for help is a gut wrenching moment to hear?
