When TC gets out of Magnum's car, he is wearing a red shirt ripped up from the fight at the gym. The viewer can see he is being followed and is taken by Mano's thugs. When Magnum is also grabbed and brought to Mano's house, TC has a new black dress shirt on.
When delivering the painting to get the girls back, Magnum has to climb over the gate to get into the War Memorial. When the kidnapper picks up the painting and leaves in his car you can clearly see the entryway next to the gate is open.
