I just got back from having a great time at a local IDPA club match, and a shooter was given a flagrant penalty based on rule 5.2.2.C "Not fully engaging all targets as required". The stage had five targets that were to be engaged with three shots each while moving down range. The shooter engaged all targets with two rounds and was penalized for points down plus the FP. No competitive advantage was gained, and it was clear the shooter had a "mental malfunction". Is this a proper application of the FP?
