If they were involved an operation to export thousands of guns to Mexican drug gangs[1], surely killing hundreds in the process, then yes. If they knew, they probably wouldn't intervene. Even still, few (any?) Lulzsec attacks actually leaked unencrypted credit card data. Even then, the damage done by exposing credit cards is pretty negligible anyway.
