I'm trying to travel to amsterdam.can felons be denied when entering amsterdam

I have been reading that you have to be careful in Amsterdam because they are cracking down on tourists smoking weed and some other things that they use to be liberal on.

Here is one article
Dutch Conservatives Crack Down on Coffee Shops | DrugReporter | AlterNet (http://www.alternet.org/drugreporter/42891/)

I hope somebody knows about your traveling there

I am pretty sure it is okay
