There have been over 125 protests against asylum seekers in the city so far this year.
The Justice Minister says people who cross the line between fair protest and abuse of asylum seekers will be punished by the law.
Simon Harris says those who engage in violence like the burning of tents seen on Sandwith Street will be prosecuted.
He's spoken to the Garda Commissioner about the policing of protests and is confident the force is well resourced.
Speaking in the Dail this morning he said : ''If and when that line between protesting and threatening or intimidating behaviour are crossed there are a number of provisions in our laws which applied. We are also strengthening our legislation in this area with our new criminal justice bill which we are hoping to enact this year.''
