You don’t have to have a cane for that to happen. Anyone can get pulled aside. It’s happened to me numerous times. If you really want the experience travel to a place on one airline with a one way ticket and back with another airline without luggage. I did that going to Chicago for a day trip and got check at security and was again pulled aside when boarding the airplane. Four very thorough security checks in one day. They had my name on a list.
In my case it was because I cannot walk without my shoes on so I had to be "special" screened.
