Dirty commiegang lawyering would be dope, I donno how easy it would be to setup a communist indie lawfirm group that just crowdsources knowledge and info to help proles. Something like a red NAACP but better and even more of a PITA for the booj. Anyways gonna post the little I know, I just have a rough idea on how to build a case not the details.
So you can find legal codes on some kind of law search website like this, https://codes.findlaw.com/LCsearch.html#?cludoquery=drug%20trafficking%20in%20ca&cludoCategory=Codes&cludopage=1&cludorefurl=https%3A%2F%2Fcodes.findlaw.com%2F&cludorefpt=U.S.%20Codes%20and%20State%20Codes%20-%20FindLaw&cludoinputtype=standard
Then I assume when you have a bunch of codes relevant to your case put together, you find ambiguities in the wording to build a case, or any other contradictions to other laws cases etc.
Then there are also legal court form websites to find forms you can file with the local courts. I assume the goal is to flood the court with documentation and evidence to make your case look strongerhttps://www.uscourts.gov/services-forms/forms?k=motion&c=All
Also legal letterheads is good to have for sending threatening emails in the likes of something like thesehttps://www.canva.com/letterheads/templates/law-firm/
And then for filing case documents specifically there's like a legal format with correct line spacing and all. I guess this is where you put everything together and explain it in word form.
The state court websites have a list of forms available to file with them too.
I guess the most important part is filing appropriate discovery papers so you can gather and request any information from your plaintiffs to dig holes in their case/get info you need. The goal being to find something they fucked up on or didnt follow due process on.
It would help if a real leftypol lawyer was here and could tell us the tools of his trade and go through step by step what needs to be done for a case
