John,
I agree completely that it is best to discuss this rationally. So let's do that.  You have a fear of  "data-basing", specifically referring to public security cameras, which presumably would be operated by Eugene police. You have referenced "the government", presumably federal, keeping a database of public security cameras (which doesn't exist) which would have to be collected from thousands of municipalities all over the country through a program (that doesn't exist) that would require a data storage facility that would dwarf the size of all current facilities. And in this imaginary database there is imaginary facial recognition software (that doesn't exist) that is cataloging your every movement downtown and building a profile on your downtown eating and drinking habits. 

John, we have a very serious (and very real) problem downtown, with harassment and violence towards women. Installing cameras is a very reasonable proposal to help alleviate that. It's not about you John.
