The laws are the way they are.<p>The laws are the way they&#x27;re written, and the way they&#x27;re read, and open to discussion and revision on both sides. If you&#x27;re upset or threatened by that (and I can&#x27;t see any other reason for some of the gratuitous hostility in your comment), perhaps your position isn&#x27;t anywhere near as strong as you might like your bluster to communicate, and perhaps it would be better to find some less distressing activity with which to pass time than discuss it on the internet.<p>&gt; the police can detain you if they have reasonable suspicion to believe you are involved in a crime in any way<p>This isn&#x27;t the point of contention at all. That&#x27;s whether it&#x27;s reasonable and legal to deny detainees access to a toilet on the basis that they <i>might</i> escape or <i>might</i> destroy evidence.
