After the fact, no terrorists acts occurred, but the protests in the Ukraine overshadowed the Olympics, and we all know what happened when the Olympics were over, and the limelight was gone from Sochi. As far as the Olympic village, seems like it was well controlled, but they were not completely finished with some accommodations at the start. the most important was the athletes had the chance of their lives, and hope they all just blocked out all the negatives.
Russia is not the USA, or UK, or Beijing, they did their own thing in their own way, and the rest of the world were guests. WE may not like their laws, but all that was feared about openly gay guests, never came to be. Stray wild dogs are a problem, which we do not see a lot of in the USA like this, roaming the countryside. They do not have people like PETA who would demand, every dog be rehabilitated and placed into homes, they may very well have hunted them to kill them. Cruel as it sounds, they are not part of natural ecosystems, and probably bring diseases into the woods and forests. Even in the USA, you are no allowed to take domestic dogs into the back country of Yosemine, Sequoia, or any National Parks, even if they are tame and have shots.
