I read some things about bitcoin xt lately. Some say it helps NSA with catching online criminals.
How do they do it now? What is the patch?

I think it has to do with IP's and tor, here is a better explanation:

I also I've read Hearn and Gavin wanted to introduce some sort of checkpoints were you would need to go through to validate transactions and then you would also have loss of fungibility due colored coins. Someone needs to do an EL5 of all of this for the non super geeks.
