I go to HEB and I NEVER go shopping unarmed. How many people in the Boulder, CO store do you suppose were armed? I don’t know how many people in my HEB are carrying but I am guessing the percentage is higher than a random store in Boulder, CO. You don’t have to be a Wyatt Earp to fire at some a-hole trying to kill people but you do have to be armed to do it. Even if you fail to neutralize the a-hole you will likely distract them and allow more people to get away.
King Soopers is owned by Kroger.
Kroger bans Open Carry customers in all its stores.
Concealed carry is allowed.
Ditto.
