This is true but even for strict liability crimes there may be vagueness problems unless you can show some degree of at least a very general intent.

The problem here is that the prosecutors hold a lot of sway over how much Presumption of Innocence should be relaxed in each case, as they are the ones who advise the governments of local jurisdictions about these matters. That would be like the umpires always being on the payroll of the home team. I'm not so sure this situation is conducive to a level playing field.
