Teach Students To Recognise a Liar

Politics, especially American politics, has a nasty tinge.
Americans vote for liars, and vote for them again, even after their lies are exposed.
Nixon, Reagan, Clinton and now Trump have all been caught telling barefaced lies and have been allowed to get away with it.
None have been punished at the polls for merely telling lies, and none have gone to jail.
Trump told packs of lies even before he was elected, and people did not recognise his lies, or did not care, which is worse.
Many children take a meaningless subject called PHSE. We should use some of this time to teach them when people on TV – especially politicians – are telling them porkies.
Hopefully enough of them will care to not vote for them.
