On the phone so not sure if copy and paste works so well so search google for police
St1300 pan and look at the wiki link. Uk for es bought the 1300 wholesale on the back of the success of the st1100 but resulted in a big fail for Honda due to wobble and weave instability at speed. Would also say that this also affected some Beemer k's back in the day but increase in power etc over the years made it more prevalent. I think two gardai (now psni) also died.
Gardai - police service of the Republic of Ireland.
PSNI (Police service Northern Ireland) was formerly the RUC ( Royal Ulster Contsabulary).

ST1300 problems iirc were sudden violent speed wobble which even highly trained police riders couldnt control. Possibly thought to be confined to police spec bikes - due to equipment used and how it was installed affecting weight distribution ?
At the time Honda continually denied there was anything wrong with the bikes whether civvy or Police spec. No idea what the final outcome was tbh.
Although if I had read the more recent posts above I would have had more of an idea of the outcome.
