The Taoiseach has said he is concerned and frustrated at the growing number of protests outside the homes of politicians.
It follows a protest by a group of people wearing masks outside the home of Minister for Integration Roderic O'Gorman late last week.
Simon Harris also pointed out that a protest took place outside his home in 2017.
He added that a number of other TDs and the home of Sinn Féin leader Mary Lou McDonald have also been targeted.
Speaking on RTÉ’s Today with Claire Byrne, Mr Harris said he wants to know if existing laws are robust enough and if they are, "then I need to know if gardaí are empowered enough to enforce them", he said.
"What I want clarity on this week is a very simple question. Is this a matter of enforcement or a matter of law?
"In other words, are the laws that we have robust enough and therefore they just need to be enforced?" Mr Harris said.
He added that he does not believe Fine Gael has lost control of law and order, but understands that people do feel unsafe at times, particularly at night time.
Mr Harris's comments come as the Garda Representative Association begins its annual conference where gardaí will discuss what they say is an increase in assaults on gardaí, politicians and others online and in person.
Mr Harris said it is not his job to tell people they are safe, but to make them feel safe.
There are number of ways to support gardaí and make people feel safe, Mr Harris said, including establishing a taskforce in Dublin and increasing sentences and garda numbers.
He voiced his "full support" for Minister for Justice Helen McEntee. Mr Harris said she is doing a very good job and has a proud record of legislative change.
He added he was very pleased to reappoint Ms McEntee as Minister for Justice and said that his appointments were not based on personality but about delivery and the ambition to do more.
Meanwhile, the Taoiseach has said it is ridiculous to think that the Government can deal with the issue of immigration on its own, and work must take place on a European level.
He said the country is dealing with a relatively new phenomenon and "we have to get it right".
It is important that the issue is dealt with on a European level and work on European borders and European returns agreements must be examined, he said.
The Government needs to be agile in its response to the immigration crisis and respond in real time, the Taoiseach said, adding that he "absolutely knows" that the best way to address any potential abuse of the system is through faster processing times.
Ireland was better as a result of immigration, he said, but that the State must ensure that people who come here "get a faster yes or no" once their application is processed.
Mr Harris also said there has been a significant reduction in people from Ukraine seeking State accommodation.
Around 45 people from Ukraine are leaving State accommodation every day and around 15 seeking it, he added.
Tax burden
The Taoiseach also said he wants to see an increase to the point at which people enter the higher bracket of income tax and the USC burden reduced for middle- and low-income workers.
However, Mr Harris added: "I think people want us to do better than just giving a few bucks on tax."
He pointed out that a number of incentives have been introduced to help reduce household burdens including the expansion of hot school meals, free schoolbooks and lower third level fees.
"The totality of a household income isn't just around tax," he said.
Mr Harris said he is conscious that the price of fuel is rising again but said the carbon tax is helping those on fuel allowances or those who are retrofitting their homes.
Harris defends time as Minister for Health
The Taoiseach defended his record as Minister for Health and pointed to several achievements during his time in office, including the introduction of new cystic fibrosis drugs and providing leadership during the Covid-19 pandemic.
However, Mr Harris said he takes ownership of the comments he made about children's waiting lists for scoliosis treatment.
Wait times did reduce significantly, he insisted, but they increased dramatically during Covid.
He said that current Minister for Health Stephen Donnelly is placing a huge focus on the issue.
"We have an independent task force chaired by senior counsel, we have a new clinical lead ... we have a huge amount of got going in in terms of resources and we are now beginning to see progress again."
