(i) a statement of facts establishing probable cause to believe that a
particular designated offense has been, is being, or is about to be
committed, (ii) a particular description of the nature and location of
the facilities from which or the place where the communication is to be
intercepted or the video surveillance is to be conducted, (iii) a

appear to be unlikely to succeed if tried or to be too dangerous to
employ, to obtain the evidence sought; and
(e) A statement of the period of time for which the eavesdropping or
video surveillance is required to be maintained. If the nature of the
investigation is such that the authorization for eavesdropping or video

observation has been first made, a particular description of facts
establishing probable cause to believe that additional communications or
observations of the same type will occur thereafter; and
(f) A full and complete statement of the facts concerning all

or places specified in the application, and the action taken by the
justice on each such application.
3. Allegations of fact in the application may be based either upon
the personal knowledge of the applicant or upon information and belief.
If the applicant personally knows the facts alleged, it must be so
stated. If the facts stated in the application are derived in whole or
part from the statements of persons other than the applicant, the
sources of such facts must be either disclosed or described, and the
application must contain facts establishing the existence and
reliability of the informants or the reliability of the information
supplied by them. The application must also state, so far as possible,
the basis of the informant's knowledge or belief. Affidavits of persons
other than the applicant may be submitted in conjunction with the
application if they tend to support any fact or conclusion alleged
therein. Such accompanying affidavits may be based either on personal
knowledge of the affiant, or information and belief with the source
thereof and the reason therefor specified.
