I lived in Guam for 2 years, and I didn’t know that. Thanks.
As well...... interesting.
I was doing some research on the CNMI lawsuit, and came across the person who said they wrote the law.
I was able to get an email address, and he was gracious enough to tell me the story. He first wrote the law to ban all guns, but they ran into resistance from Guam, and modified the law to “allow” the ownership of .410 shotguns and .22 rifles.
