Did Jenny Murat set up this booth before or just after Robert was made arguido?
Before.
http://www.mccannpjfiles.co.uk/PJ/JENNIFER-MURAT.htm"Relative to the facts concerning the disappearance of the English child, the deponent states that because she has been in Portugal for a long time and knows many people, she decided to mount a "post" to collect information in order to be able to determine things about the subject and thus could channel them to the competent authorities. For three days (Friday 11/05, Saturday 12/05 and Sunday 13/05) she was at the "post" mounted near to the cinema having obtained some information that she gave to Robert who, in turn, gave it to the Police.
--- Her idea was to try to sensitise people not to feel intimidated by the presence of police and lead them to give all the information that they knew."
On Sat 12/5 & Sun 13/5 RM thought his vehicle (presumably the Hyundai) was being followed.
http://www.mccannpjfiles.co.uk/PJ/MICHAELA_WALCZUCH.htm"Asked she relates that she noticed no difference in his behaviour, either from the day(s) 3-4 May, or in the last 3 days. She continues to note that he is "upset, concerned by this whole situation of translating, picking up details that nobody else knows, that he hears, in addition to the situation about which he is already sad" (sic). Asked on the same question, she answered that on Saturday, when they dined together, and yesterday, Sunday, on the telephone, ROBERT showed "naturalness and normality even when on both those occasions he said to her that he perceived or suspected that a car came behind him, glued to him", without attributing suspicion to the police. She clarifies that she cannot manage to recall if he told her that the possible followers were Police. She advances, with difficulty, that ultimately Robert had tried to clarify the matter with the police itself. This fact was transmitted in a phone call that she received from him at 00:00 today."
On Sunday 13th VW used at information post was reportedly washed.
http://www.mccannpjfiles.co.uk/PJ/MICHAELA_WALCZUCH.htm"--- Asked, she states that on the 13 May last she was with Robert washing the VW Transporter at GALP-Lagos because it was dirty."
On Sun 13th PJ request warrant to search his premises & vehicles.
04-Volume IV, pp. 995 to 1001
On Mon 14th at 0720hrs PJ enter Casa Liliana.
We can only speculate whose idea it was to set up the information post 8 days after Madeleine's disappearance. I can recall from the news footage at the time that the green V/W could be seen with its rear door open & there was a mattress on the floor in the back. That seemed odd at the time, as Mrs Murat was sitting at a table nearby.
