Of course I would. Accused pick pocket is not a convicted pick pocket, so limiting his access to funds is immoral. Not sure about the legality, to me it absolutely should not be legal but I do not have enough knowledge to claim that it is. To better illustrate the problem with your devil's advocate approach ask yourself the same question adding in the words in brackets: would you permit a person (wrongly) accused of being a pick pocket to use (his) funds (incorrectly assumed to come) from stolen wallets to pay for his defense?
