A police official says One Nation Senator Pauline Hanson might have undermined police efforts to "build social cohesion" when she donned a burqa in a stunt in the Senate last week.  Greens Senator Sarah Hanson-Young went even further and said the next terrorist attack in Australia will "be on your head, Pauline".

Appearing on Channel 7's Sunrise news program, Senator Hanson-Young said provocative stunts like wearing a burqa into parliament to call for a ban on the clothing do nothing but alienate members of Australia's Muslim community.

"You're doing ISIS's work for them.  It is extremely dangerous.  You're putting the entire country at risk," said Senator Hanson-Young, pulling no punches.  "You say you are worried about security yet you refuse to listen to the advice from experts.

"The next attack in Australia will be on your head, Pauline."

Hanson was stunned, and later in the day demanded an apology.

Ms. Hanson-Young's critique added new urgency to what most mainstream politicians have already said since last Thursday's stunt.  Attorney General George Brandis last week said Hanson's mocking of the clothing favored by some extremely devout Muslim women was "appalling".  PM Malcolm Turnbull backed Brandis and added that the Muslim community was the best, "indispensable" ally in rooting out jihadist extremism. 

And on Monday, Victoria Police assistant commissioner Ross Guenther confirmed that assertion.

"I think things such as that don't obviously help with our drive to build social cohesion," said Mr. Guenther, as quoted by The Guardian.  "We work really closely with community leaders here in Victoria, as they do in other states, and things like that tend to undermine that process, I have to say."
