Perhaps, once we know what the candidates are, we can write to them and make suggestions on how to fix things. There are calls for Mandatory 5 + year prison terms for those who carry knives, so we should challenge the candidates to say what they would do if they don't agree with that idea.
If we suggest extreme ideas, because we are sick to death of people seemingly getting away with things, e.g shoplifiting but not JUST that threatening behavior against staff, harsh punishments.
We need to work out what we want prisons to do, if they are there to remove a person from society, they in general NEED to rehabilitate that person, fix what ever issues they have (e.g addiction) education and job training so upon release they are in a better place. Prisons can't also be a revolving door either. Prisons need to be fit for purpose, built for 21st century not victorian buildings. Build new prisons, convert old prisons to accommodation OR pull them down and build affordable social housing.
In terms of health care staffing crisis, when I was in Canada (2006) there were adverts on TV promoting health care training courses in Georgia (USA). I felt this was a good idea, pro active, get out there and say we need doctors, nurses etc, so provide fully funded courses, the caveat is that they owe the Taxpayer (NHS) 10 years service at least.
Yes this is expensive, so tax the rich, tax the corporations and give regulators proper powers to enforce. We can't keep having raw sewage released in to water courses during dry weather for example and can't keep letting big tech get away with things, fine big tech, give some of that money to the fediverse and other foss projects.
