Oh those boys. Don't they realize that it's b/c you brought their album nad love them so much is the reason they are popular? Okay okay, I get it. Some fans can be crazy and they need to be safe. So they went and hired the former boyguard of the President to protect them during their upcoming tour!
A source says:
"They will be protected by some of the best security personnel America has to offer… There is significant concern that the group will be greeted by mobs of thousands of girls, which is too much for the normal team to handle. To make matters worse it is the US school holidays too."
