Speculation abounds over whether 'Whitey' Bulger will testify during his racketeering trial

Lawyers for James "Whitey" Bulger will begin calling witnesses to defend him, but the big question is: Will he testify?

Bulger is charged with playing a role in 19 killings during the 1970s and '80s when authorities say he ran the Winter Hill Gang.

Some lawyers not connected to the case say Bulger has too much baggage to testify. Others say the 83-year-old may decide he has nothing to lose.

Judge Denise Casper asked Friday if Bulger would testify. Bulger attorney J.W. Carney Jr. said only that he would let her know after his other witnesses testify.

The Boston Globe reports Bulger's attorneys filed a motion late Sunday seeking to have the jury sequestered when it begins deliberating. The defense cites the "extremely prejudicial" coverage by the news media.

The defense case begins Monday.
