I suppose it was bound to happen in the home of litigation and confrontation. However as an ordinary punter I can see reasoning behind taking this action. If investors put their money into a company (any company) and the leaders of that company took an action which adversely affected the company share price then those at the top should reasonably be held accountable - I would have thought. It might even amount to fraud, as it would be taking money on false pretences.
To be honest it would be good if the Dolly the Sheep cloners could do a job on Hewlett and Packard and bring them back to run the outfit. It's not the same company as it was 20+ years ago, they seem to have a problem putting people into the top job.
