Search exercise planners handbook – Part Six

November 24th, 2009

How many clues can you find?

I often hear of search exercise planners and Training Officers trying to add motivation to an exercise by ensuring that there are loads of clues dotted around for teams to find. There are two comments I have regarding this practice;

One; In the lowland search environment it is extremely rare to find clues that are useful to the search management team. Why? Because the environment we search in is generally well-trodden already. There are no lack of potential clues in any urban, sub-urban or even rural setting in most places in the UK. Everywhere you go you will find discarded clothing, litter, drinks cans and so on – none of which is useful, as the SMT cannot tell if it is the mispers or not. Compare this to a search in the wilderness of the US, where few people have been in the last year/two/ten years!

The one potentially useful clue in our environment is track and sign, which can, with a skilled tracker, be given a useful time frame – Passed here in the last couple of hours or the grass would have totally sprung back up, walked here before/after the rainfall six hours ago and so on. This is doubly so if there is a comparison print available, or even shoe type & size.

The second comment I have upon using clues for exercises is that it reinforces the wrong behaviour. Searchers are “rewarded” for finding every clue, not finding the missing person quickly. As such searchers have tended to search closer together and slower – sweeping up everything in their path. This is done to the detriment of the overall search effort and success of the search. [Greater information on why this is so can be found in the paper, Spaced Out Searchers]

Care needs to be taken then, when deciding whether or not to use clues in any exercise. Generally, my advice would be, if in doubt don’t put any out!

This is even more important when searchers are being assessed – either for their basic search techniques course, team leaders or re-assessment. I would want to know that the individual could search for a misper, NOT find and sweep up litter!

Are PolSAs the right resource for managing missing persons search?

November 12th, 2009

A while back I wrote a briefing paper, Spaced Out Searchers, that formed the basis for the ALSAR Conference presentation, Advances in Lowland Search Techniques. In it I discussed how ALSAR Units search techniques had changed because they were working with PolSAs who, because of the experience of search tended to want areas “cleared”.

To understand this you need to understand the main role of a PolSA. The role of a PolSA is to provide Chief Constables advice on the management of low-risk counter terrorist and explosive device search. That is, they search for devices in situations where there may potentially be devices, but that it is not suspected – for Royal visits etc.

When dealing with explosives you want to be pretty sure you haven’t missed anything so PolSAs and police offices trained in search are trained in terms of absolutes – either there is something there, or there isn’t. This works well too in the extension of the PolSAs work with evidence searches. Again, SIOs want to be confident that something is either there, or not.

However, as I stated in the paper, this takes time and resource. In order to have that level of confidence a PolSA will use whatever amount of resource for whatever length of time is required to achieve it. Missing person search is different. Time is critical; the misper is dying as time goes by – just take a look at the survivabilty figures for the evidence! And, unlike a planned operation, you only have the resources available to you there and then [which are never enough!]

This is where the mathematics of search theory comes in to play – allowing the optimum use of those resources available to you over time. [I will write a series of posts on this soon.]

However, the concepts of probabilities must be extremely difficult for officers trained in searching in absloutes to get their head around – especially when in one search one thing is called for, then in the next search which might even be during the same operational period or day, another search style needs to be used.

A radical thought came to be yesterday – why do we then train PolSAs to run our missing person searches? Why not train other, non police search trained officers to run missing persons searches?

I’d love to hear your thoughts;
