Gritz traveled to Pinellas Park, Florida, in mid-March in an attempt to make citizen's arrests of individuals involved in removing the feeding tube of Terri Schiavo, a Florida woman diagnosed as irremediably brain damaged.

In a press release titled "True Grit(z) rides again,"  Gritz announced:

Former Green Beret Commander Bo Gritz is charging-in once again. The 66 year-old retired Army Lt. Colonel with his wife, Judy, drove straight through from their Southern Nevada home to Pinellas Park, Florida in their own effort to rescue Terri Schindler-Shiavo. In his typically unconventional fashion, Gritz is arresting Pinellas Circuit Judge George Greer [who ruled the tube should be removed] and Terri Schiavo's estranged husband, Michael Schiavo, plus anyone else who would aid or abet in removing Terri's feeding tube.

Gritz, who did not know Schiavo, said he becomes involved in public controversies "when it appears Americans are in needless life-and-death situations with the law."

"Most people wisely don't arrest important officials, it can be non-habit forming. It's my contribution, as I see it," Gritz said.

On March 18, he handed the warrants to authorities guarding Schiavo's hospice. The following day he and three others were arrested for trespassing as they tried to bring bread and water into the hospice in a symbolic effort to feed Schiavo. He was released the following day.
