Re: wtf does not "freeing prisoners unlawfully" mean ?
Actually, it is. And an English one.
Past participle of "[to] get".
Just that England/UK itself stopped using it a few centuries ago. Aboutttttt the time America was first settled by them. The Murrcan language today still has words, grammar, and pronunciation which were standard at that time, transported to America then sorta "frozen", which have since fallen out of usage in Britain.
Given your chosen monicker, I find it amusing you were unaware of that.
