The destructive power of high power microwave (HPM) generators allow them to be used as effective weapons by both law enforcement and criminal organizations. Now, with the desperate need for cash by some developing nations, devices such as relativistic magnetrons, capable of producing multi-megawatts and for use in weapons, have been offered for sale to other nations, groups, and individuals. Hence, HPM weapon capability has now become available not only for military use by any nation wishing to invest but by terrorists and other criminal organizations. Similarly this capability is now available for law enforcement activities. For the most part, it is believed that the aforementioned high multi-megawatt powers would not be necessary for law enforcement. Powers in the tens to hundred kilowatt range should be adequate, and tailorable sources such as microwave transmitters readily available.
