Feds Tracked Down an Anti-ICE Dad in NYC Hotel, but How?

From the article:

"Financial surveillance by law enforcement is far from unheard of, but it wouldn’t be normal to see agents use it in this way. For instance, ICE in particular once had widespread access to something called the Transaction Record Analysis Center (TRAC), used to surveil immigrants who wired money, but much of that access was clawed back last year amid public scrutiny and accusations of illegality."

I'm 100% positive there is more evidence in these cases than is covered by the rag known as Gizmodo.
