sa katong case nga nasakpan sa mall, dli ko totally agree sa decision ato. yes, tinuod nga the car is a private property and its an "extension" of your home. but its also true that a Mall is a private property. so by that logic, if the couple had every right to do whatever they wish sa ila private property, so do the Mall owners and that right extends to the security guards, they being tasked to look after the peace and safety of the establishment..
though adto mag pundok ang mga taw, Malls are still considered private property. mao bitaw wala CITOM inside their area. mao bitaw maka compel sila nimo mu open sa imo sakyanan before you enter the parking area because you are entering a private property. they don't need search warrants for that. lahi pud nang parahon ka sa checkpoint, duha ka search ra pwede ana. Plain View rule and Stop and Frisk rule. dli pwede mu utingkay ang mga pulis og walay search warrant.
going back sa topic, its not illegal to copulate in the car. however, if nag park ka in a public place den nasakpan ka, pwede kag disturbance of the peace.
