I hate this topic and all these speculations on what will happen.  It's pretty useless and rather lame given that people in Texas are losing their homes & everything, and the Prez is pardoning a proven racist criminal.  Get some perspective people.
That said, if "sensitive" negotiations are re-opened, Ainge should ask for something else back too.  I mean, why not?  Perhaps a pick swap instead of just giving them an additional pick. The Cavs are not exactly in the best negotiating position.
OMG. agree on the texas stuff but last i checked illegal aliens are not a race even if the vast majority are a certain dempgraphic! breaking the law is breaking the law regardless who is doing it, get a clue! Go look at the list of people obama pardoned for perspective.
This is quite off topic, but just to clarify, that sheriff was not punished for targeting illegal aliens. He illegally targeted all non-whites, regardless of suspicion, in order to look for illegal aliens, and continued to do so after being ordered to stop by courts of the land despite being a law enforcement officer. That is undisputed, but seems to be the tip of the iceberg; there is overwhelming evidence and settlements that he did all this at the expense of investigating actual crimes, like child rape, etc. 
In summary, he was tried and convicted for violating constitutional civil liberties of US citizens and refusing to stop doing so after he was caught and ordered to stop.
