Research Tools and their Effectiveness - Essay Example The research took more than 26 weeks to complete. With the sensitivity of the matter, training them for only 8 weeks doesn’t make a lot of sense in that they will not have experienced the necessary knowledge which they can use with ease to determine whether to report as casualty or not.
