these measures do not follow the usual due processes.
For many reasons. Among them the limitation of security clearance not to jeopardize the process and the information or the target. The second one even a judge needs a lots of evidences to be declassified in order to give the warrant and sometimes needs to be done immediately, The third , some of the operative action do not fall under the direct constitution and needs some kind of amendment in order to operate before getting the green light.
The forth but the most difficult part, if not handled with care and absolute patriotism, it creates infringement to the basic human right act and can not be justified at all in the court of law as just.
I will give some example, to clarify this point. For example the American CIA uses Rendition. which is since the USA law do not allow to water board or any form of Torturing of prisoners any kind. USA collaborate with some foreign governments for torturing's their suspects. Egypt, Syria, Ethiopia under TPLF, Afghanistan, Yemen and more other countries were partners to accommodate CIA agents to come to their countries and torture citizens and aligns for forced confession.

On the other hand to protect the nations integrity usually most governments have a special intelligence department special forces who are operated at faster pace than the judicial system and under the publics radar in order to apprehend, stop or kill foreign agents and mercenaries, and drug cartels and Gangs. As a result the foreign operative will be afraid and be more careful and increases their operating coasts to a level that needs a second thought for their government. On the other hand criminal groups like OLF, Shene and TPLF should not enjoy the legal protection the same as normal civilians.
This special force should have the power to detain, even take out agents who are trying to destabilize or hurt our integrity and existence, for example the spy Davis Wadley and other westerns operatives who pretend to be journalists should be arrested, interrogated or disappeared with out acknowledging it and the evidence could be presented at any time later through the under world not with normal diplomatic process.
We should be able to arrest and interrogate any foreigner with out any warrant if they found to be subspecies of any economical, financial and espionage crimes indefinitely and search their premises. In this way the western will be forced to acknowledge their presence and open their underworld channel for negotiation secretly, as they did in Libya, central Africa, Mali, than the usual Diplomatic channel where they have the upper hand, over our cadre diplomat who have no clue about diplomacy, that they use to communicate to the JUNTA and other anti Ethiopian entities through their agents in the media and aid groups.
