If a person "enables" money laundering, that person is a money launderer, not a conspirator nor are they aiding and abetting.

They are facilitating a scheme and that is an offence as principal.

Tell it like it is: call them money launderers and prosecute them as such.

If "naming and shaming" is to have any effect, it needs to have punch. Joe Public doesn't care about woolly terminology. But he does care, at least to a degree, about money laundering. Make it easy for him.
