I don't support illegal activity, but I believe this is a quest of freedom, not for getting stuff free as in free beer.
Why don't you support illegal activity?
Are you morally free to kill your guards if you are in prison through a failure of the judicial system? I don't think you are.
How about if you are in a death camp, where your government has not made a mistake, but is executing its legislatively determined plan of genocide? I think you are morally free to kill your guards in that case.
I also think you are morally free to rob a store for medical supplies during a natural disaster, but not morally free to rob a bank to pay for a relative's life-saving surgery.
When to break the law should be a conscious decision, consistent with some framework of ultimate costs and benefits to yourself, your society and beliefs, not merely opportunism or a universal refusal to ever defer to the rest of the community's decisions.
