To be fair that’s cos it’s a nato meeting. Americans probably don’t have to put up with this stuff much cos the country is so big, but the whole visiting world leaders shit is a fucking pain in any and every european capital. Loads of roads get shut and the cops do be out in force and take no shit. He probably won’t be charged or anything but any sign of trouble at events like this and people start getting carted off immediately to protect the image of the city/country.
