Well, we may never be able to rely entirely on less-lethal tech. Some situations are just too risky to take the chance that someone will keep attacking after less-lethal weapons are used on them. Most notably, a person wielding a firearm who is, say, blinded with pepper spray may panic and start firing in random directions. A person on PCP, a drug known to delay pain reactions, may not even notice if they&#x27;re hit with one of these bullets.
