I agree with you, but would also say carrying this was is still better than not carrying at all. Carrying this way is still a powerful Deterrent

60 percent of felons surveyed admitted they didn’t commit crimes if they were aware potential victims were armed. What’s more, 40 percent of the surveyed felons reported being discouraged from committing crimes if they simply suspected potential victims were armed.

But yeah if you were targeted by a criminal, surprise is probably a better indicator of whether you are going to be a victim or not.
