They didn't give you that stuff so you could resell it. It was for your use in the course of your employment. Yeah, I worked in an ER too, but the most stuff I'd end up with my pockets were a few tourniquets and maybe a quickcath or a red top or two, and I didn't attempt to sell any of this stuff.
Them letting you out without bail does not mean anything on your criminal charge, just that they suspect you will make your next court appearance without them having to dangle the threat of revoking the bond over you.
