This issue needs to be handled by a corporate lawyer or executive. Please bump it up the chain.
I've read an email from Jesse at your Customer Care center saying that PetSmart prohibits customers & employees from lawful self-defense, but I know that stores do not take any steps to ensure the safety of those disarmed customers and employees in the store or parking lot.
I carry my pistol every day, lawfully & peacefully. The only person to whom I am any threat is the one trying to harm me.
I will no longer buy from PetSmart until you rescind the policy. As a private property owner you have the right to exclude almost anyone for almost any reason. As a private citizen I can choose to not spend my money in a defense-free zone, & I can tell my friends not to shop there.
Criminals will disobey your store rules just as they disobey much more serious laws against robbery, assault, murder... And in fact, experience shows that criminals prefer to attack where they know people won't be able to defend themselves effectively.
Please make PetSmart like the myriad of other businesses across the country that simply follow the law wherever they are. If the gov't there does not prohibit the lawful carry of a pistol for self-protection, the store should not either.
Please send me a copy of the current policy & notify me when it is changed to allow self-defense. (And if it's copied from an employee manual, realize that it doesn't apply to customers, so you need to re-train your staff.)
