Citizenship revoking

[Bobsmyth]

Hi Bob,
I may have not understood the reason why his citizenship was revoked. From reading the post, it seems like his citizenship was revoked because he was convicted of selling crack after he became a citizen. I was not aware that after a person becomes a US citizen, breaking certain laws can result in their citizenship being revoked.
Am I reading the post correctly?
Thanks!

He was charged with drug trafficking before the oath, but convicted after the oath. The conviction meant that he did not meet good moral character requirement and was therefore denaturalized.
