Walking home alone

[SamDobson2]

Hi. I have 2 sons aged 7 and 9 both in the same school
I live less than 100 metres from the school gate
The kids cross one road to get home which has a lollipop lady on it
I wrote to the school to say that I want my kids to walk home from school
The kids will be home alone for 30 minutes till an adults gets home
They refused saying it's school policy not to let's kids go on their own
It's not law
It's my decision
The school keeps refusing
They wrote to social services after they questioned one of my sons and found out that the kids are alone at home
For 30 minutes
After several calls between me and social services they finally saw no issue with the set up I have and wrote a letter to confirm this
The school still refuses
I wrote to the chair of governors
Heard nothing back yet
What can I do ?
Can I call police if they refuse to let kids go ?
Should I see a solicitor ?
Can the school do this or is it an abuse of power taking my children's liberty away from them after school ?
Please help

@letstrythatagain Unfortunately times have changed particularly due to the increase in traffic in most areas.

I have friends and acquaintances who successfully fought their children's schools to allow their children to walk home at age 9 (going on 10) a longer distance and with more roads to cross than what the OP mentions. However no-one fought for a younger child to do the same.

I do know the clubs and activities that I've looked at don't allow children under 8 to go home alone, and some of my friends and acquaintances who fought for their children to walk alone have been involved in some of these.

@caban I know parents where SS have threatened to. Unfortunately for the social workers involved they haven't realised that the parents they are bullying are educated, know their responsibilities towards their child(ren) and know what rights the social workers have.
