i do wonder why they are calling on civilians. they have 150+ (i've seen upwards of 200) agents on the case. surely some are probably doing more of the 'desk' work like analyzing tips, social media, digital stuff, etc. but certainly they could call upon a good chunk of those 150-200 to get out there on foot. why ask residents/civilians?
i think it might be partly public relations public like to feel like they are doing something to help. Probably heard that at the town hall. Also most of those LEO are professionals with expert training in certain areas better not to waste those peoples time out in a field if the public can do it.
