Collaboration for HSINT

  What do you think are the two largest obstacles or challenges preventing effective multi-agency and inter-governmental collaboration for intelligence support to homeland security operations?  This question needs to be answered from two perspectives….a strategic one and a tactical one….Are there legal issues that need to be addressed that have not been? Also describe at least two solutions or effective frameworks that are being used (or that can be better employed) to overcome these obstacles and ensure effective inter and intra-agency collaboration for intelligence support to the HSE.  *500 word minimum with citations and references
