I bet the car was stolen nearby and had a base sticker on it, and the perps thought that they could just drive around freely on the base with out anybody checking them out. The base cops probably knew about the stolen car and was on the look out for it, a stolen car with a base sticker would be very high risk situation, in which a lot of base security people and local cops would be on the look out for.

Your hunch about the car having a base sticker is probably good.

I found this sentence on the linked TV report interesting:
“[Maricopa County SHeriff Office] said Glendale police investigated a SECOND vehicle associated with the Litchfield Park “.[emphasis added by me to the word ‘second’]

Depends on what Luke is doing these days. The Majority of bases have done away with base stickers since 9/11. Entry onto the base is 100% ID check now.

they did away with the base stickers for just the reason you stated.
