Dahua is now going out to delete these references but again it's very clear and unsurprising that Dahua, like any other large commercial video surveillance provider would intend their products to be used by law enforcement, government entities, etc.
Again, it is simply marketing and adjusting to the changing business climate. When the laws change, so does the marketing approach. Just because they were marketing to law enforcement in the past doesn't mean they were wrong then and doesn't mean changing their marketing now to not include public safety and law enforcement doesn't make them liars - they changed their marketing approach and targeted market based on new legislation...They even told you in their reply to you they are not marketing NDAA agencies.
Cigarettes used to be marketed and endorsed by doctors. The Flintstones were in cigarette ads as were other cartoons. NASCAR was sponsored by a cigarette brand. Cigarettes used to be on commercials on TV. Then the laws changed and they had to change their marketing approach... Lots of industries have to change their marketing approach based on changing laws.
