Don't be silly.
According to you, a kid picked up for marijuana possession could be tortured to find the sources, who else is using it and so on.
Torture does more violence to the torturers than to the tortured. Look at what the US has become.
And torture has not produced Iraqs nukes, WMDs, democracy or stability.
Anyone advocating barbaric behavior is, truly, barbaric and beyond the reach of human decency.
