Now, i might be talking out of my ass here since im a terrible chemist amateur, but if i understand it correctly, riot shields are made of polycarbonates. They are relatively easy attacked by aromatic hydrocarbons and ketones, from which benzene, toluene and acetone are readily available in hardware stores. Wouldnt it be worth considering buying some of those chemicals and throwing it at them, if it weakens their shields quite well?

Everything of that in minecraft, of course.

edit: after looking around a bit more, PMMA, a polymer that substitutes riot cars windows often, is also easily attacked by it. :curious-sickle:
