LYNN – A Lynn man has been ordered to serve at least six months behind bars for yelling racial slurs at an MBTA inspector while trying to assault him in April 2010.Daniel Jourdet, 53, pleaded guilty Monday to assault and battery and violating a person’s civil rights as his trial was set to begin at Boston Municipal Court. Judge Mark Hart Summerville sentenced Jourdet to two and a half years in a house of correction with six months to serve up front and the balance suspended for a probationary period of three years. If Jourdet re-offends during that time, he could be ordered to serve out the remainder of his sentence.If the case had proceeded to trial, Assistant District Attorney Kate Clayman would have introduced evidence and testimony to prove that the 34-year-old victim and another inspector saw Jourdet and another man yelling and pretending to fight on the Copley station inbound platform the night of April 1, 2010.The victim had asked Jourdet and the other man to stop their behavior or leave the station, but instead, Jourdet yelled racial slurs about the victim’s ethnicity and threw a punch at him before leaving the station. The victim was not injured, but his hat was knocked to the ground.”During the assault and throughout this case, the inspector kept his cool,” said Suffolk County District Attorney Daniel Conley. “He’s poised, perceptive, dignified and intelligent – in short, everything this defendant is not.”Jourdet was represented by attorney Lucy Rivera.
