A historical artifact was stolen from a museum display case. The security camera showed a person wearing a heavy raincoat and sunglasses walking out with a bulging backpack at noon on a bright, cloudless summer day.

Anyone could wear a raincoat as a disguise
A criminal attempting a disguise would willingly wear a ridiculous outfit like a raincoat on a sunny day to conceal their identity and body shape from cameras.
