HOMELAND Security Minister Roger Alexander says the roll-out of the 30 army-police posts is on track to meet its four-month completion time frame.He said the project is being accelerated as the Government seeks to strengthen public safety and security.'Some of the units, people working them possibly this week and going forward will continue to proceed across the direction; it's about public safety. So, we must ensure this happens. We have a time frame to work with, and we are working with that time frame,' he said.He was answering questions from the media yesterday at the official opening and ribbon-cutting ceremony of the steel plant by Ibis Steel Company of T&T Ltd, Pt Lisas, Couva.Asked whether US security personnel could join local officers on the ground at the posts, Alexander declined to provide details, suggesting that additional measures could be announced later.'Some things you have to leave as a surprise; it's about having the added advantage. So, I will leave that for the mind to think,' he said.Alexander also confirmed that the structures have been designed with reinforced framing, which he said would make them difficult to penetrate.Asked whether the posts were bulletproof and capable of withstanding the elements, he said: 'They have some framing, and in that framing, it is very difficult to penetrate.'He said the focus was on ensuring both the safety and security of officers using the facilities and the wider public.The minister declined to disclose the cost of the individual posts, saying details would be provided in subsequent announcements.'As I said before, all that we'll discuss is in subsequent announcements. So going forward, right now we are just thinking of the safety and security,' Alexander said.The roll-out has attracted criticism from some quarters, with questions raised about the design and implementation of the posts.Asked about the criticism surrounding the initiative, Alexander defended the project, arguing that the criticism was expected and that members of the public were still seeking greater security measures.'You expect anything other than that, really?' he said.He questioned whether elected representatives who were criticising the initiative had adequately consulted with constituents before doing so.'However, in those people's constituencies, they are calling and asking for these things. Who are they speaking to? It seems to be a conversation in caucus,' Alexander said.He maintained that Government's priority was to respond to public concerns over safety and security while continuing with the planned roll-out.
