If he/they was making an "anti gun control statement", he/they would be targeting gun control advocates, anti gun politicians, law enforcement, the media, the families of the above, and possibly those in anti gun demographics ( minorities, women, clergy, etc.).
All attacks seem to be random, except for the craft store and gas station repeats.
Instead of sending "I am God" taunts he/they would communicate the "message"[puke] at each shooting somehow.
IMHO he/they are fruitcakes or terrorists. Death penalty will be waiting, when they are caught![:(!]
