Water cannon, riot police and more arrests of dissident Republicans and extreme Islamists are all expected as Ireland prepares for its biggest security headache ever in preparation for Queen Elizabeth II and President Obama's visits over the next ten days.
Starting today Irish police are launching a major security operations into action.
It has been announced that up to 10,000 police, along with Defense Forces, will be deployed in Dublin, Kildare, Tipperary and Cork during the State visits. The police have also announced that they are closely monitoring the activity of dissident republicans and supporter of groups such as al-Qaeda.
The Irish Times has reported that thousands of police with riot training and dressed in riot gear will be shadowing the Queen and Obama "in anticipation of violent protests during their visits".
According the Superintendent John Gilligan the Queen's visit, from Tuesday to Friday next week, will be one of the largest operations undertaken by the police force.
The main focus of the Irish police is preventing public disorder. Police in the south and the PSNI are both fearful that dissident republican will plant hoax explosive devices to cause disruption, especially during the Queen's visit.
The police have already borrowed a water-cannon to use on large crowds of rioters during the Queen's four-day visit. They have also hired coaches to transport thousands of police in riot gear from location to location during the visits.
The police believe the major locations of risk are the city centers of Dublin and Cork. These are the locations that have the potential to turn into riot situations.
On Tuesday the Queen will visit the Garden of Remembrance in Dublin and Croke Park on Wednesday. Both events will be very heavily policed due to the potential for hard-line protesters including militant republican groups. A republican group, Eirigi, are already advertising their protest at the Garden of Remembrance.
The streets surrounding the Garden and the Croke Park stadium will essentially be shut-down by the police. Riot squads will be ready at all times, out of sight just streets away.
The Queen will visit Phoenix Park to meet President Mary McAleese at her residence Aras an Uachtarain on Tuesday and will also visit Farmleigh , the official government home on Thursday. Similar security operations will be in effect in these areas.
