Heck, we can trust Congress to use well-established, unadulterated definitions in legislation, right? Just take for example the word 'assault rifle'. Everyone knows that an assault rifle is a magazine fed rifle that fires a high power cartridge and--this is the key characteristic--is capable of fully automatic fire. The military, the experts on this type of weapon, has used this definition for almost 100 years, so its the standard. Surely no legislator would redefine the word to exclude the fully-automatic fire description, and arbitrarily add non-pertinent characteristics in order to suit their own agenda, right?
Hey, does that PTSD legislation also take away a person's driver's license, as they cause massive casualties far more easily in a 4000lbs mass traveling at 60mph than they can with a firearm?
