content: EMP blasts (directional EMPs aren't really a thing without a really big faraday cage)  can't be used within populated areas due to health risks (pacemakers, filtration machines, ect.) and signal jammers are against FCC regulations and carry a heavy fine (in the US at least, there are similar laws in other countries with wireless internet). The only way to handle this situation is to call the police, they'll come along and shoot it down, protected by criminal equipment laws that allow them to damage or destroy property being used for criminal intent, and then they'll take it away.
