With technology advancing at a rapid pace, police are trying to stay ahead with the latest tactics and technology. One of the latest tactics to see an incredible boost in tech is surveillance. Police are now using IMSI catchers which are portable surveillance tools that monitor cell phone use. They can be used to track location and intercept calls, messages, and data. Vice News went to the United Kingdom to investigate the police usage of these IMSI catchers. What they found was quite amazing and disturbing at the same time. At one point they went and scanned for catchers at a peaceful protest and discovered evidence of a police catcher moving through the crowd. They then visited a trade show where these catchers were sold and finally they found a black market salesman who is willing to sell to them. With this new technology comes great privacy concerns and if criminals get their hands this new tech then who knows what will happen. Either way technology is getting scary advanced.
