Assata Shakur? The terrorist? Of course she did not "find a safe haven here in the U.S." while she and her Black Liberation Army were shooting people and blowing up buildings. The police were trying to put her in jail.
"just"? The BLA was shooting people and blowing up buildings, no scare quotes needed, they actually did that. That is why the police were after them: they were breaking the law in a serious way. How confused do you have to be to say that they should not have been investigated for these crimes because they were doing something else also?
