What happened to the Prime Minister in Canberra was disgraceful by any measure.

Pictures of a frightened Ms Gillard stumbling in the arms of a her bodyguard went around the world.

What a shameful image to project of a nation renowned for its democratic traditions and non-violent politics.

Whether the Aboriginal protesters were angry at Opposition Leader Tony Abbott’s comment about the tent embassy is irrelevant.

There was no excuse for hounding the two leaders aggressively and Aboriginal leaders were quick to condemn what had happened.

It also insulted the recipients of the National Emergency Medal receiving their awards in the restaurant.

Another, quieter protest was conducted outside Parliament House yesterday.

Sadly that was marked by the burning of the Australian flag, the foremost symbol of Australia.

It is difficult to envisage an action that would lose more public sympathy for the Aboriginal cause.
