1.	Local police should only be allowed to use StingRay devices if they obtain a warrant for the use signed by a judge. They should not be allowed to use the devices without judicial approval because it would then be an infringement on the 4th amendment to the constitution which protects citizens from unreasonable search and seizure. Police have used these devices to collect data and monitor the cellphone use of innocent citizens who have never been accused of a crime. These devices should only be allowed to be used if it is on a single suspect who has been accused of a crime and who's had a judge sign the warrant for the spying of.

2.	For the most part, no. Use of federal anti-terrorism funds is generally being misused when it's being used on innocent American citizens in mass gatherings of data by police with these devices. If the police were using these devices on a suspected domestic terrorist, that would perhaps be a more appropriate use of the funds.

3.	Nothing on Tyler PD's website indicates whether or not they use the StingRay device. This is unsurprising given that most local police departments who use the device often refuse to disclose anything about their use of it. They cite their Non-disclosure Agreement with Harris Corporation, the maker of the device, as the reason for their lack of transparency.

4.	Recently, the Washington DC Court of Appeals ruled that the use of evidence obtained from a warrantless StingRay interception was not admissible in court. They say the reason for this is that the suspect in the case they were overseeing had his Fourth Amendment rights violated when the local police tracked his cellphone without obtaining a search warrant from a judge.

5.	In the future, any devices that local police wish to use that are intended to collect and gather data on people should only be allowed to be used if the police have received judicial approval via a search warrant. If they do not adhere to this, they will be infrining upon citizens' Fourth Amendment rights. The public should absolutely be made aware of the use of these types of technologies as much as possible. Use of these devices should only be kept secret if not doing so would pose a risk to an officer's safety or to the public's safety as a whole. If that is the case, the police need to prove why it would be a risk to disclose the use of such technology.
