The recent suspected terrorist attack on London Bridge demonstrated how fearless members of the public used their initiative, reacted selflessly and risked their lives to prevent, what could have been, a more serious situation. It appears the public are growing tired of individuals who want to cause harm and are taking matters into their own hands. This is not always the safest course of action and not one that should be encouraged, each situation is different but if you are backed into a corner and your only option is to fight, react immediately and commit to the offensive.
