If Bamber walked to & from WHF, then he walked. As I said it would take him 50 minutes. If he jogged, 30 minutes. So not difficult for a 24 year old man.
However all supporters & guilters will agree that it was a massive coincidence that Bamber brought over June's bike just before the massacre. And his reason for bringing it over is one of the most ridiculous things I have ever heard.
