If you've ever been to a major sporting event in the Bay Area in the last several years, you'll have noticed in most cases a sizable police presence. This is true regardless of the size or reputation of the venue. Police and traffic control are costs either borne by teams, municipalities, or a combination of both.
It's also not a surprise that like many other cities in California, Fremont is in a serious budget crunch. In Chris De Benedetti's recent article, Fremont City Manager has flatly stated that the city is in no position to fund additional infrastructure for a ballpark/ballpark village. So who would pay for this infrastructure if the deal were to go through? Don't discount the idea that in bringing the A's in, city leaders are pushing Fremont residents to rethink current infrastructure-caused service blows, such as the burglar alarm policy.
One more thing - Tuesday's election day! It could be potentially very important for the A's future.
