There's a certain bias many people have; let's call it "the illusion of safety." That is, believing things they think should be secure actually are. In some cases, that belief is so strong nobody even bothers to make it illegal to, say, sneak into a very important building, like a King or Queen's palace. It's just kind of assumed that would never happen.
Sure, we'd all like to believe it takes some combination of Danny Ocean and Tom Cruise to get into our most "secure" facilities, like the White House. But many times, a little bit of patience, a lot of bravery, and an axe will do just fine.If history has taught us anything, it's that there's no such thing as truly "safe" or "secure." One determined person can make mincemeat of the best-laid defenses. It takes an entire forge to make chain mail, but a single arrow to find its weakness. That's how people can sneak into a building like a nuclear power plant. Here is a list of people and groups that broke into places you'd never believe it was possible to gain access to - with minimal effort.
The United States
America is a big country and big places aren't usually that difficult to sneak into. There are a wealth of options for sneaking into the US, whether it be sneaking across one of our borders with Canada or Mexico or just hopping on a plane and never returning to your home country. Determination goes a long way.
Back in 1982, Queen Elizabeth awoke from a nap to find what appeared to be a drunken homeless man standing by her bedside, dripping blood on the carpet. The fellow's name was Michael Fagan, and he had (for the second time that week) climbed a drainpipe and entered the Palace through an unlocked window. The blood was from an ashtray he'd cut himself on while stealing a $6 bottle of wine from the Queen's stash. Afterward, he meandered into her bedroom and chatted with her for about 10 minutes until a maid found them. Fagan wasn't charged with any crime aside from stealing a bottle of wine, since it had never occurred to anyone to make breaking into Buckingham Palace illegal.
Red Square (During the Cold War)
In 1987, a daring young lad from West Germany had a brilliantly suicidal idea: to end the Cold War by flying his tiny Cessna airplane into Russian airspace, landing right in the middle of Red Square and giving the Russians and NATO something to talk about. And he did it.Despite flying right through the Iron Curtain, supposedly some of the most heavily defended airspace in the world, and fully expecting to be shot down by a squadron of MiGs, 19-year-old Mathias Rust piloted his small plane right to the Kremlin's front door and landed in Red Square like he owned it. People were fired. And by "fired," we mean "shot." Mathias did succeed in a way, too; at the very least, his infiltration proved that Russia was nowhere near the dominant military power it still played at being, and Gorbachev "tore down that wall" a short time later.
People have been breaking into the White House for ages; one of the most notable was a fellow named Charles Dickens, who broke in after President John Tyler took too long to answer the door.
The Secret Service regularly has to deal with unwanted visitors, mostly in the form of tourists wandering about. There have been several cases of tourists splitting off from tour groups and wandering around the mansion. Granted, most uninvited guests don't make it past the lawn these days due to all the sophisticated electronic surveillance. But break-ins and attempted break-ins still happen on a pretty regular basis.In 2009, socialites Tareq and Michaele Salahi infiltrated a dinner party at the White House and got their pictures taken with President Obama and Vice President Biden before being found out.
