The psychosis that leads an unsub to resort to a naked attack can arise from many situations. A mixture of alcohol and schizophrenia can cause a similar effect depending on the underlying sexual frustration of the unsub. PCP can cause the same effect in addition to extreme rage.
The worst of its kind are Haitian mushrooms, which has led to the most brutal massacre and cannibalism of victims, in most cases, friends and families of the attacker. On coming to their senses, the attacker has no knowledge of his actions.
We need to be really careful when dealing with such situations. Trying to calm the person down or even use mace or tasers may have no effect on them. People under the influence of certain drugs can possess the strength of 4-5 men. The Haitian mushrooms I mentioned before were used in war long ago by the Scandinavians, where they would go so insane, that they would tear apart the enemy with their bare hands.
So yes, if I ever see a person naked and trying to attack, I will get out of there. If the person is attacking someone with intent to kill, I will take them down.
There is no way anyone can control them in their state.
