The Justice Minister says she is concerned there may be a paramilitary display at the funeral of Vincent Ryan tomorrow.
Mr Ryan was shot in an apparent gangland style assassination in Dublin last week.
Although he was a staunch republican, his family say he will not have a military funeral.
When his brother Alan was buried - balaclava clad men & women in paramilitary uniforms, accompanied the hearse.
Justice Minister Frances Fitzgerald says gardaí have been in contact with the family ahead of the funeral.
"That obviously is a concern and the public, I believe, are appalled at those type of displays.
"An Garda Síochána will take every step possible to ensure that there is a dignified funeral.
"Certainly the public do not want to see that kind of display, sometimes it is quite difficult, but I believe the Garda Commissioner has been in contact with the family and they have expressed their wishes to her."
