I find the new rule for shooting through windows and the whole "clarification" thing to be in questionable due to IDPA stated objectives of not changing rules. If they are going to just send out email blasts and post rule changes on the IDPA Forum there can't be any "stability of rules". It appears the rules for IDPA have become a moving target. This is particularly bad when a shooter is heading to a major match particularly if they don't have an email or access to the web.
