hiding in ambulances, oops to be more politically correct it's "taking cover" in ambulances, is now a unique world crass invention and copyright of spf. every police department on the planet has taken notice of the new best practice. but most likely none will follow or copy due to spf's possessive and protective nature of their inventions....and discovery under duress. must say that spf truly think "inside" the box rather than the old tired matra of thinking "outside" the box. for this alone, commander must be rewarded and promoted for the spontaneous innovative group-think.
