Make that 50 years, at least. While it wasn’t murder, Teddy did get expelled from Harvard for cheating and then for paying someone to cheat for him.
He went into the Army, came back, and was once again enrolled in Harvard, bought and paid for. I remember when it was revealed, several years after it happened and he wanted to run for Jack’s former Senate seat.
He was the baby of the family, fifteen years younger than Jack, for instance, and spoiled rotten. Then there is that tendency for the line to run to seed. Joe Jr. was the ablest, than Jack, then Bobby, and then you-know-who. All spoiled in some way, but Teddy cracked under the load. Bobby’s death probably broke him. He—thank God—has never aspired to any thing higher than his safe seat in the senate since he ran off that bridge.
