It's an assult here, regardless, to a citizen by other citizens.
Waterboarding may or may not be torture (depending on who you believe). But, if it's something you're willing to have done to yourself in training, I tend to think it's probably ok to use for interregation of non-citizens. I'm ok with stun-guns and tear gas, so I'm basically ok with water boarding.
I'm not ok with cutting off fingers or toes. But, I'm pretty sure we don't do that in training, either.
This was a crime pure and simple purpetrated on a helpless senior citizen by two lowlifes
