Bikes are cheap. Cheap enough to be basically disposable. You can get them off craiglist for cash. They're quiet, and you can take routes (like alleys, utility corridors, walking paths) that are difficult/ impossible to patrol other than by foot. A rattle can of black spray paint is like, $12.
Nitrile gloves. Wrap one inside another like a sock and you can stick 2-3 of those in a back pocket. They aren't cheap, but they are way better and more durable than latex. Get the ones auto mechanics use. They have a left and a right; you'll hardly notice them.
Speaking of pockets; fucking empty them. Don't bring one unneccessary item.
Poopysuits are basically disposable. You can get them as cheap as $25 online. They come in all different colors, colors like black and dark blue. They can be worn over other another set of clothes; perhaps clothes that one would never, ever imagine going to some place and doing some thing. If you spill anything on them, your clothing underneath is much less likely to be impacted.
Look at each of these cases: License plate readers; finger prints; identifiable clothing.
All, very, very easily mitigated for.
