During a community event which usually has police on hand because of crowds and traffic; parades, holiday tree lightings, park concerts etc, local GMRS licensees may be attending the event or could be organized specifically to keep an eye out for any and all emergency situations. The Community radio group would coordinate frequency and other pertinent info regarding the participants etc to the police authorities. The best case scenario would be repeater operation so that all calls to the police could be to a control station/dispatch. All calls would be to the police dispatch would then contact the officers Patrolling the event. This of course requires the complete cooperation of the police. They would have to tune radios to GMRS frequencies. They would have to want to do this. I interpret the emergency use provisions in the GMRS rules to allow such use. I suppose the legitimacy of the Community radio group would have a lot to do with whether or not the police would want to partner with them. Thank you to everyone who has given input.
