"My issue with this is that there was no cross-party consultation and that the situation has changed from weapons being held at a base with the need for authorisation from a senior officer, to weapons being carried on regular patrols which means the chain of authorisation has been removed. Can you genuinely not see how that is different and why it raises concerns for some people?"
I'm a bit late to this discussion, but firearms were never held at the base until there was a call. What possible use would the firearms be in a base? Either your officers sit at base all day twiddling their thumbs, or if you send them out to earn their pay, then on getting a firearms shout they would have to hare back, get their gear, and THEN go out.
Firearm crews have modified cars, which depending on force areas have lockers either fitted in the cabin or the boot which contained the sidearms (pistols). The guns are always in the car. Locked up, but with them. In the unlikely but serious event that you get a report of an active shooter in the vein of the Cumbrian Shootings, you need to go straight there - not via a half-hour detour (if you're lucky) back to base. That's what they're basing this on - the once-in-a-decade occasion when you wish every single officer was armed.
On being called out to a shout, they would - as standard practice - open that locker and equip themselves with their sidearms, because presumably if they were being called on at all, it was for a suspected firearms shout. They never needed higher authority to get their sidearms out - they were being sent to a job because they were armed. That's the entire point.
Opening the big box in the boot that held their MP5/G36 rifles (depending on force area and roles) would be following approval by head shed on a case by case basis, although exact procedure may vary force-to-force.
All the new practice says is they carry their sidearms as standard practice, even if they're assisting a non-firearms shout. Nothing more. It's not more guns on the street, more armed officers, nor anything else. They're just carrying them routinely instead of leaving them in the car. And they were always in the car, never back at base.
Scotland IS NOT going from a scenario where guns were solely held in an armoury to where they are being routinely carried on the streets. You've got it into your head that they're making a much larger policy change than they actually are.
If you go to pretty much any other country in the world, all Police carry sidearms all the time. A minor change in when the small number of armed response units do and don't carry their guns is of no real consequence whatsoever. Just because the Daily Record wanted to hype it doesn't make it significant...
