Narrative:

I was completing my final passenger compliance walk-through while we were taxiing out to the runway for take-off. I picked up trash throughout the cabin and went back to the aft galley to throw away the bag and double-check the B flight attendant's (flight attendant) galley latches. I opened the trash cart and realized that the cart was full. This was the first flight of the day and there had been a security checklist completed that I handed to the gate agent when I closed the door. I told the B flight attendant that the security checklist had not been completed correctly if the trash cart was not emptied.I immediately called the flight deck and told the captain what we had found. The aircraft stopped while the captain was on the phone with flight operations. They were trying to decide if we should pull back to the gate. The first officer (first officer) and I searched our manuals to find out exactly what the procedure was for completing a security checklist. We were instructed to return to the gate.when we arrived back to the gate; the captain was talking with ground crew through the flight deck window. The supervisor on duty tried to contact the supervisor from the previous night to find out if the paperwork was filled out wrong or if security had not been completed on the aircraft however; they could not reach the employee. The decision was made to deplane all of the passengers and conduct a thorough security check.multiple ground crew came onboard and assisted me; the B flight attendant; the captain and the first officer in completing the security checklist. The captain later informed me that as we were pushing from the gate; he heard over the radio that the aircraft at the gate next to us possibly had a security issue as well.I cannot say for sure that an aircraft security checklist was falsified. However; I do know that the security checklist was completely filled out stating that the entire aircraft had been searched. In addition; the aft trash cart was full which means that was not inspected.
