'Ebullient' Cohen Reveling in Insider Trading Ruling

``Now it won't be enough just to show that traders relied on "material non-public information" to buy or sell stocks. Prosecutors will have to prove that traders have complete knowledge that the information they used was of the illegal variety, and that some sort of gift of "consequence" was exchanged with a tipper to get the insider information... Depending on how many cases are overturned, the 2nd-Circuit ruling might deal a political blow to Bharara, who compiled a near perfect record of insider trading convictions during his 5-year crackdown. Bharara has political ambitions, people who know him say, such as possibly running for governor of New York.''
