Your ID card or else...
In the USA, in Denver, people are facing prosecution for not carrying ID documents on an ordinary cross-town commuter bus. The bus runs through town and transits the edge of the Federal Center ( a complex of buildings, not a security sensitive site). Police are boarding busses and demanding IDs of passengers. A woman who refused to give such IDS has been arrested and will face court on 9th December . Just a cautionary tale perhaps on how things can escalate, to throw into our own ID card debate?
