It takes courage to say what you honestly feel, even when you are fully aware that you will be pilloried for it - including by some of your friends and colleagues.
We have been here before, where those who object to statements being made and actions being taken on the basis of insufficient or suspect evidence, are reviled and spoken of as cowards, traitors and fools.
If there is an attempted murder, there is usually a careful examination of all the events surrounding it - what happened before and after the incident, where did it occur and how was it carried out, who are the individuals that are suspected of having carried out the attack, is there evidence to indicate that they committed the crime on behalf of another person or organisation, etc. etc. Even what appear to be fairly open and shut cases of attempted murder/murder usually take weeks for forensic evidence to be obtained and examined, detailed witness statements taken, etc etc.
