honestly an unarmed human doesn't stand a chance against a large predatory cat (mountain lion/cougar, tiger, panther, leopard , jaguar, etc.) that has the intention to kill; or any large predator for that matter.
kenpo is designed for street fights. real combat situations require the use of dangerous, fast and effective techniques. kenpo acknowledges that there are only two rules in street fights - no hitting above the head or below the feet , so of course there are no rules. I believe kenpo to be a great real combative MA but it does depend on the person.
