I would remain badgeless with the exception of Class A uniform or PR events, Seems to me most people see a badge but cannot recognize the fact you are indeed an EMT/Paramedic, Just yesterday I had to attend a PR event and if you can imagine I had several people mistake me for law enforcement, in the hood this could be a problem. keep a low profile and dont give freddy the hood rat anything to shoot at, trust me and stick with badges for funerals and other such special events.
