Do private investigators carry guns in London?

Private investigator UK often is not allowed to carry weapons, and doing so without the right documentation and training is against the law. Government regulations on the use of firearms by private investigators are strict, and only licenced and qualified individuals, such as security officers, are permitted to carry firearms. So it's unlikely that private investigators in London will get access to weapons while conducting their investigations. Instead, they rely on their education and experience to compile evidence and conduct their investigations in a morally and legally correct manner.
