Why do the Tory's not admit that they could have saved all the lives at Ladbroke Grove train crash?

the report chaired by Anthony Hidden QC (27th september 1989) recommended that automatic train protection was fitted to our trains. so the tory party had many years in power to act on this so they and only them killed the people at Ladbroke Grove. So what do you think the tory party should do as they could have saved these lives. So if you think labour killed our soldiers in Iraq by cost cutting and you will not vote for them, will you vote for the tories who kill people on trains by cost cutting
