Obvious question, why didn't the gun store report any of this? If a gun store was rammed with a car, and had their ammo and weapons stolen, you would expect them to call the police and report it.The illegals graduated from ramming stolen cars into convenience stores to steal cigarettes to ramming gun stores to steal ammo and weapons. Likely all stolen.
Let me come up with an alternative theory. Maybe two Mexicans came to the USA, and bought 180,000 rounds for about $40k, with the expectation that they could sell them in Mexico for about $200k. Maybe they do this on a regular basis, and have profited well from it. Maybe the gun store loves the business.
