Officers at Singapore’s border checkpoints will have an enhanced set of questions to interview visitors, in an effort to better detect those who pose a risk to the country and, if needed, prevent them from entering the island.

This Security Screening Questionnaire is being developed by psychologists from the Home Team Behavioural Sciences Centre working with the Immigration and Checkpoints Authority and academics from the Portsmouth University in Britain.

… Professor Rohan Gunaratna, head of the International Centre for Political Violence and Terrorism Research, Nanyang Technological University, believes they are necessary.

“It is essential to develop tools to detect radicalisation and militarisation by tracking those visiting extremist and terrorist sites,” he said.
