Reichberg, a Hasidic Jew from Borough Park who  is referred to as “CC-l,” is termed an unindicted co-conspirator. Both were  donors to Mayor Bill de Blasio, whose 2013 campaign appears to be the ultimate  target of the federal probe. 
The complaint adds  that Rechnitz introduced Seabrook to a hedge-funder friend, Murray Huberfeld,  with whom Seabrook invested $20 million of the union’s funds. In return,  Huberfeld, through Rechnitz, allegedly paid Seabrook a $60,000 kickback. 
Huberfeld, of  Lawrence L.I., whose family foundation has donated millions of dollars to Jewish  charities and yeshivas, was convicted of fraud in 1993 after he had another  person take his broker-licensing exam. In 1998, he and a partner paid $4.6  million to settle a civil complaint brought by the Securities and Exchange  Commission that alleged bank fraud. 
All this looks bad  for Banks, but has he done anything criminal? To prove criminality, prosecutors  must establish a quid pro quo. Banks’s free trips may have been a quid, but so  far we have seen no quo while he was a member of the department. 
Both Bratton and his  predecessor, Ray Kelly, accepted free airfare. In his first tour as  commissioner in the 1990s, Bratton took free plane trips from Wall Streeter  Henry Kravis; and Kelly from his boss, Mayor Michael Bloomberg, who flew Kelly  to his second home in Deerfield Beach, Fla., on his plane. In Bratton’s case,  then-Mayor Rudy Giuliani used those free trips to suggest Bratton had done  something untoward, and forced his resignation. 
So what’s the  difference between Bratton’s and Kelly’s free trips and Banks’s? Perhaps due to  naivete, Banks’s four trips were taken with FOUR CROOKS — one of whom paid for  all of them. 
More damning  information regarding his relationship with Rechnitz comes from Banks’s  disclosure statement after retiring from the NYPD. In it, he indicated he  earned between $250,000 and $500,000 from investments with Rechnitz, suggesting  something improper. Closer scrutiny, however, reveals that the sum is what he invested with Rechnitz. 
Similarly, the FBI  has reportedly scrutinized Banks’s bank accounts, revealing thousands of dollars  in monthly cash deposits. Sources point out, however, that similar deposits go  back to 2000, indicating they were unrelated to Rechnitz, whom Banks met more  than a decade later.
