Not necessarily. It is very likely that Shinseki found he did not treat this problem with adequate seriousness, or even found evidence he knew about the lists.
Someone's head had to roll, and this was probably a good start. I want to see disciplinary action at the actual VA Medical Centers where these deaths occurred. Whomever allowed these lists to exists while submitting doctored statistics should face criminal prosecution for fraud at the very least.
Someone besides the Administration needs to investigate all of this at VA to find out exactly what has been going on. That someone needs the power and authority to look at every single VA Center across the country and since there are deaths of service members involved, that someone needs the ability to bring specific criminal charges as appropriate. That all means that another Select Committee ought to be formed to look into the long history of abuses at VA. The committee can request a Special Prosecutor if need be as well.
Time to start playing hardball on this.
