Remember? The place where Belloc wrote, in a wry mixture of pride and horror, "Whatever happens, we have got/The Maxim Gun, and they have not," knowing that Civilisation was a thing worth protecting?
Yeah. They're not so much that way any more. In 21st-Century London, "protection" = "oppression." Plus, ew, cooties -- "do it to Julia," and elsewhere.
Update: Some understandable debate in Comments. From my reading, those complaining are renters -- sorry, if you wanted more control over who else got space in your building, you should have owned it. As well, what's UK law on this kind of thing? If the Crown is acting in a manner consistent with the laws of the land, well -- those laws might be wrong, but there they are. If you object, you might be better writing a letter to your M.P. than on a website, better filing suit than waving signs.
There's even discussion of OMG, what if they rilly shoot a hijacked plane down and it falls on London? In answer to that, two items: 1. Like making it fall will create more damage than allowing it to reach its intended target? 2. Ever hear the words "deterrent effect?" I believe the present tendency of airline passengers (especially in the U.S.) to dogpile persons who act up on airplane flights has done more to prevent hijacking than all the efforts of TSA -- not because actual hijackers are being stopped in the act but because even a fanatic can see the odds are poor. If you want "poor odds" demonstrated, try "airliner vs. modern AA." An Airbus ain't a V-2. Anybody remember the Israeli policy in re hostages?
