Marmaset

I recently burnt my hand and developed a well sized burn blister. It's look normal for about a week but in the past 2 days seems to turned into a blood blister. The swelling is steadily going down, and it's not painful, so the blister has seen some agitation though nothing that could pop it. Can these normal blisters turn into blood blister, and if it was never popped can they get infected, and does it sound like it's infected?

I am fairly certain it's not infected but just want some clarifications, if a blister that seems to be getting less swollen, and not painful, but turning into a dark red, dark purple be healing okay by itself? Most important question is the title question.

So I understand that some anarchist support Private defense agencies to help against crime, but i can't see how this works for other types of Anarchy. And don't say it won't exist because no one will be poor. There are numerous reasons people steal that aren't poverty induced. Not only a&$holes but kleptomaniacs and plain selfish people. Give at least some broad overview on what could ethically occur.

Basically take the portafilter, add a dash of pot, grind the coffee over it, and brew as normal. My theory is if it is on the bottom the espresso will have enough fats to extract the THC.
