This is a predictable reaction from an incumbent one month away from a competitive election. It is not a failure of democracy for one arm of government to react like this - it's a failure if that populist whiplash becomes policy (or is debated seriously enough to spook).
An analogy would be October 2012, Romney is hot on Obama's heels, and a shooter goes on a rampage in Times Square. It would not be unexpected for the President to call for greater monitoring, no limits to what will be done to safeguard the American people, yada, yada. Norway's reaction was anomalous in the shooter being Norwegian and the political climate being mellower than France in an election year.
