Though the fact that it's basically vandalism is still concerning. But the photos only show door damage, not sure where those $numbers are coming from.
I wonder how you would react if the police would take e.g. your car under the pretence of "we think you might have been speeding" and after six month you still have not have your car returned, or been actually fined (or taken to court for speeding). But the only comment on a forum is "well he should have been speeding".
This is just theft. How is this legal?
Police investigate before they press charges. Investigation involves gathering and seizing evidence. On a national security matter I would expect them to be thorough and tight-lipped.
In most nations simply attempting to photograph the base at all, whether trespassing or not, would be criminal. For all their problems the US feds are legally required to tolerate many activities that would be plainly illegal in most nations. The Snowden documents circulated because it's not illegal in the US for regular civilians or newspapers to view or distribute classified material, only those who are military or have a clearance (and no need to know) are forbidden. Elsewhere state secrets laws define that activity to be universally criminal.
As subjects of the King, canadians have no understanding of liberty, nor the founding principles of the American nation. They fled as soon as people suggested defiance. Subjugation is in the veins of canadians.
