In Australia, there is a strong presumption towards keeping left as a pedestrian (and overtaking on the right - e.g. etiquette on escalators is to keep left, but if you are walking up the escalator, overtake to the right).
In some particularly busy places (especially on shared footpath / bike lane zones) there are even arrows on the pavement to ensure tourists know what side to keep to.
There are always a few people (probably tourists) who don’t follow the local etiquette.
I think the whole case seems super suss.
The photos of someone in the area look nothing like him.
But supposedly they found him days later, based on someone recognising him (from what? he doesn’t even look like the publicly shared suspect photos), and despite him supposedly having travelled a great distance - enough to scatter any evidence over large distances where it would never be recovered, he happened to have a complete set of evidence on him, including a paper “manifesto” and the weapon. That seems like a rather unlikely story. And then they try to seek the death penalty, and double up federal and state.
I think what happened is the authorities decided they probably would never find the real killer, but it was also unacceptable not to have someone to blame - they’d rather kill an innocent to send a message than let crime against the rich go without a response. So they picked some random they didn’t like and set him up.
