ASA and FED took "intent" out of the rule in question because too many umpires were using that as an excuse not to call interference when warranted because..."I'm not a mind reader, I don't know the runner's intent..."

The instruction to the umpire is to now judge the actions of the retired runner. As stated, the retired runner cannot simply disappear once they are put out. The runner has one specific task...run to the next base, a specific spot on the field. The fielder can use the entire area of the playing field to make a throw. The retired runner has to "do something" besides continue to run to the base in order to interfere.

I find it ironic that the NCAA philosophy taught to umpires on interference with a defensive player fielding a ground ball almost requires physical contact to make an interference call, but they don't have a problem with fielders throwing directly at retired runners.
