The US Civil Rights Movements in many states have a major downer of police airborne cameras [and UAVs] and in particular the ability to see through walls. Some states have major issues with the right to search by IR - even accidental searches have been ruled illegal.
Rubbish perhaps but the MSP images may yet play into the hands of Civil Rights simply because it was demonstrating an ability to see through walls.... in this case a tarp.
It will be interesting to see what balance there will be between the popular ability to capture the Boston Bombers and the political 'needs' of the Rights community.
