Thieves who forget about security cameras often also forget they can get caught. These criminals in Buenos Aires, Argentina surely must have as they repeatedly are seen stealing phones from passengers on a moving train. This is something we haven't quite seen before as the accomplice points out someone with a phone just ahead, giving the other time to reach through the open window. Karma is catching up to them as one man is seen being arrested.
In most circumstances, attacks can hardly be predicted which gives the attackers an unfair advantage.
Four gentlemen sitting down for lunch at a pizzeria in Russia had only glanced at the menus before a group of several large men began wailing on them. This mafia-like scene is startling to watch as they're all bought to the ground and kicked. While three men remained injured but OK, the other can be seen leaving with the attackers.
